Slide 1: A Taste of TWiki

A Wiki is like a web site, except that you can edit the content in your browser

• "Wiki" is short for "wiki wiki", the Hawaiian word for "Quick"
• The idea originates from Macintosh Hypercard, via Ward Cunningham
• In Ward's words, Wiki is "the simplest online database that could possibly work"
• A Wiki is basically a shared, online, persistent whiteboard

Slide 2: TWiki Wiki

• Anyone can add content
  ... or change what is written
  ... or change the organisation of the content

TWiki also acts as an "application platform" to integrate a number of other functions.

TWiki is an Open-Source development on TWiki.org

• led by TWiki:Main.PeterThoeny
• with over 100 regular contributors in many countries

Slide 1: Where is it used?

• Examples: Disney, British Telecom, SAP, Wind River, Motorola, Epic Games
  

A number of public Wiki sites also use TWiki

• Examples:
  https://twiki.cern.ch/twiki/bin/view/
  http://wiki.java.net/bin/view/Javapedia/WebHome

Slide 2: TWiki Features

• TWiki pages are fully revision controlled, so a record of every change to every page is kept

  r6 < r5 < r4

• The look-and-feel is highly configurable, through use of templates

A "plugins" interface eases customisation extension application integration

Slide 3: Applications of basic TWiki

• A whiteboard
• A document repository
• A collaborative authoring environment
• A notebook / scrapbook
• A chat room

Slide 4: Extended applications

• A Content Management System (CMS) for websites
• A presentation development tool
• A Blog
• A database
• A project management system
• A tracking tool
• (truth is, we don't really know its limits!)

Slide 5: Structure of a TWiki page

• A header
• A body
• A footer

• The header and the footer are generated by the system
• The body contains the text of the page, as entered by you

Slide 6: The Page Header

	MyCo.MyTopic	Webs: Myco | Main | TWiki | Sandbox
	Changes | Index | Search | Go

• Changes - gives you a list of recent changes
• Index - gives you a full index
• Search - takes you to a search page, where you can search all the text
• Go - lets you type in the name of a page you already know

Slide 7: The Page Header ... continued

	MyCo.MyTopic	Webs: Myco | Main | TWiki | Sandbox
	Changes | Index | Search | Go

• For example, we might have a web called "Enemies", where we keep all we know about our enemies, and another called "Friends"
• There's usually a safe play web called something like "Sandbox" or "Scratch", where you can create pages just to try things out
• And some admin areas, like "Main" and "TWiki"

Slide 8: The Page Footer

• The Edit link takes you to an interactive page where you can change the page content
• The Attach link lets you attach files
• The other links invoke other, more complex, functions, mainly to do with revision tracking - they can safely be ignored for now

Slide 9: Editing Pages

• You've read a page, and you disagree with it violently! It says:
  Everyone knows that the world is an OblateSpheroid
  But you know for a fact it is flat!
• You've clicked the edit link, and an edit page has appeared. But it doesn't look much like what was on the page before - it's full of strange hieroglyphics!

• Now what?

Slide 10: What's in a page

• The hieroglyphics are what's known as "TWiki Markup" or "formatting"
• They are a really simple way of telling the browser how you want the page to look
• You don't have to use them
  • TWiki understands pages in plain text just fine.
    
    Actually it is perfectly and absolutely flat
    
    appears as
    
    Actually it is perfectly and absolutely flat

Slide 11: Formatting just makes pages prettier

• A full description of all the formatting can be found in the TextFormattingRules and TextFormattingFAQ
• The best thing to do is just to type until you get stuck
  • then follow the link on the edit page to the help.

Slide 12: Commonly used formatting

• ---+ indicates a heading. Add more +'s for a deeper heading.

  You type	You see
  ---+ This is a heading	This is a heading
  ---++ And so is this	And so is this

• %TOC% will insert a table of contents
  

Slide 13: More common formatting

• A blank line gives a paragraph break
  
• --- on a line of its own gives a horizontal bar
• Text in stars *like this* looks like this
  
• Text in underscores _like this_ looks like this
  
• Text in equals signs =like this= looks like this
  
• Bulleted lists use three spaces followed by an asterisk (*) at the start of the line
  • The depth of the bullet is given by the number of spaces, in multiples of three

• Numbered lists use a number in place of the *. The list is numbered automatically, so you can just use a 1

Slide 14: Even more.....

• You can create a table using vertical bars:

     | Cat | Feline |
     | Bear | Ursine |
     | Wolf | Lupine |

• appears as

  Cat	Feline
  Bear	Ursine
  Wolf	Lupine

• %RED% .... %ENDCOLOR% will change the colour of the enclosed text. Lots of colours are available (%RED%, %GREEN%, %BLUE% etc)

WikiWords"> Slide 15: WikiWords

• One special hieroglyph that is very important is a BumpyWord
  • a word that starts with uppercase, then some lowercase, then more uppercase (a.k.a CamelCase)
• This has a special meaning to TWiki; if it matches the name of another topic, TWiki will automatically create a link to that page for you.
• If there is no such page, then the word is highlighted with a red-link, LikeThis
• If you click on the red-link, then TWiki will invite you to create that page.

• This lets you enter the names of topics you think should exist, but don't yet
  • You, or someone else, can always come along later and click on the red-link!

Slide 16: Referencing other pages and URLs

• BumpyWords automatically link to the target page
  • You can make these links easier to read using square brackets:
    • [[BumpyWords][bumpy words]] appears as bumpy words
• An ordinary URL pasted into text will appear as a link - http://www.google.com
  • You can also prettify URLs using square brackets:
    • [[http://www.google.com/][Google]] appears as Google
• Use %SEARCH. This is an interface to a sophisticated search engine that embeds the results of the search in your page. See TWikiVariables for full details.

Slide 17: More formatting

• There's lots more formatting available, see TextFormattingRules and TextFormattingFAQ
• If you are a real masochist, you can even enter raw HTML tags!
• Important to disable unwanted formatting, use <nop>
  • <nop>_word_ appears as _word_

Slide 18: Creating new pages

• Alternative ways:
  • Click on the red-link of a BumpyWord
  • Type in the name of the topic in the "Jump" box
  • Type in the name of the topic in the URL
• Any time you try to visit a page that doesn't exist, TWiki will invite you to create it.
• Make sure the names of topics are always BumpyWords.

Slide 19: Attachments

• Attachments are files which have been uploaded and attached to a TWiki page using the 'Attach' function in the footer.

Attachment	Action	Size	Date	Who	Comment
myco.gif	manage	9.6 K	13 Feb 2004 - 18:41	MushroomMagicMan	Attached image file

• Attachments are simply files, in whatever format you want.
• TWiki recognises some file formats, notably image files (.gif)
  • Write %ATTACHURL%/myco.gif to see this:

Slide 20: Wiki Culture

• What can I edit?
  • Anything. But it's good etiquette to sign your contributions
  • If someone doesn't want you to edit a page, it's up to them to say so, clearly, on the page
• But what if somebody doesn't like my edits?
  • In TWiki, they can always recover the old revision and re-instantiate it if they really want to
  • Otherwise they should regard your changes as an opportunity for discussion
• Pages in wiki are (usually) in one of three "modes"
  • DocumentMode
  • ThreadMode
  • StructuredMode

DocumentMode"> Slide 21: DocumentMode

• A page in DocumentMode usually comprises a contribution which is written in the third person and left unsigned.
• The piece of text is community property
  • It may have multiple and changing authors as it is updated to reflect the community consensus.

ThreadMode"> Slide 22: ThreadMode

• Thread mode is a form of discussion where the community holds a conversation
• The discussion usually starts out with a statement, at the top of the page, that is subsequently discussed
• The page may be periodically "refactored" (edited) to remove some of the comments
  • As long as the comment is accurately reflected in what replaces it, nobody usually minds.
  • Remember to always maintain a complete list of contributors, though!

• ThreadMode is rather like an e-mail thread
  • Except that new comments are usually added to the end
• ThreadMode pages often get refactored into DocumentMode

StructuredMode"> Slide 23: StructuredMode

• A page in StructuredMode follows some predefined structure for example
  • An agenda
  • A set of meeting minutes
  • A requirement description.
• Pages in StructuredMode will usually have rules governing how they are edited.

Slide 24: Other Wiki tricks - Categories

• A Wiki trick for grouping pages together
• Example: to group together a set of pages all relating to the weather:
  1. Create a page called 'CategoryWeather'
  2. Put a SEARCH that contains the word 'CategoryWeather' into it
     • %SEARCH{"CategoryWeather" nosearch="on" nosummary="on"}%
  3. Put the BumpyWord 'CategoryWeather' on all the pages relating to the weather
     (usually at the bottom, below a horizontal bar)

Slide 25: Contributed features

Here's a brief description of some of the more common plugins, together with the tags you might expect to see in topics if they are used. You can find out more by visiting the plugin pages.

• AutoCompletePlugin: Auto-complete for input fields of forms
• CalendarPlugin: Show a monthly calendar with highlighted events %CALENDAR...%
• CommentPlugin: Support rapid entry of short comments (also known as blogging) %COMMENT...
• ChartPlugin: Create PNG or GIF charts to visualize data in TWiki tables %CHART...
• EditTablePlugin: Edit TWiki tables using edit fields and drop down boxes %EDITTABLE...
• InterwikiPlugin: Define shortcuts for links to common external sites

Slide 26: More plugins

• RenderListPlugin: Render bullet lists in a variety of formats %RENDERLIST...
• SlideShowPlugin: Create web based presentations based on topics with headings %SLIDESHOWSTART...
• SpreadSheetPlugin: Add spreadsheet calculations like "$SUM( $ABOVE() )" to tables located in TWiki topics %CALC...
• TablePlugin: Control presentation and sorting of tables %TABLE...
• TWikiDrawPlugin: Add quick sketches to pages %DRAWING...

There are many other plugins, see http://TWiki.org/cgi-bin/view/Plugins

  • In TWiki, they can always recover the old revision and re-instantiate it if they really want to
  • Otherwise they should regard your changes as an opportunity for discussion
• Pages in wiki are (usually) in one of three "modes"
  • DocumentMode
  • ThreadMode
  • StructuredMode

DocumentMode

• A page in DocumentMode usually comprises a contribution which is written in the third person and left unsigned.
• The piece of text is community property
  • It may have multiple and changing authors as it is updated to reflect the community consensus.

ThreadMode

• Thread mode is a form of discussion where the community holds a conversation
• The discussion usually starts out with a statement, at the top of the page, that is subsequently discussed
• The page may be periodically "refactored" (edited) to remove some of the comments
  • As long as the comment is accurately reflected in what replaces it, nobody usually minds.
  • Remember to always maintain a complete list of contributors, though!

• ThreadMode is rather like an e-mail thread
  • Except that new comments are usually added to the end
• ThreadMode pages often get refactored into DocumentMode

StructuredMode

• A page in StructuredMode follows some predefined structure for example
  • An agenda
  • A set of meeting minutes
  • A requirement description.
• Pages in StructuredMode will usually have rules governing how they are edited.

Other Wiki tricks - Categories

• A Wiki trick for grouping pages together
• Example: to group together a set of pages all relating to the weather:
  1. Create a page called 'CategoryWeather'
  2. Put a SEARCH that contains the word 'CategoryWeather' into it
     • %SEARCH{"CategoryWeather" nosearch="on" nosummary="on"}%
  3. Put the BumpyWord 'CategoryWeather' on all the pages relating to the weather
     (usually at the bottom, below a horizontal bar)

Slide 1: A Taste of TWiki

A Wiki is like a web site, except that you can edit the content in your browser

• "Wiki" is short for "wiki wiki", the Hawaiian for "Quick"
• The idea originates from Macintosh Hypercard, via Ward Cunningham
• In Ward's words, Wiki is "the simplest online database that could possibly work"
• A Wiki is basically a shared, online, persistent whiteboard

Slide 2: TWiki Wiki

• Anyone can add content
  ... or change what is written
  ... or change the organisation of the content
• Whatever what you write is
  ... nicely presented
  ... remembered... and never forgotten

TWiki also acts as an "application platform" to integrate a number of other functions.

TWiki is an Open-Source development on TWiki.org

• led by TWiki:Main.PeterThoeny
• with over 100 regular contributors in many countries

Slide 3: Where is it used?

• Examples: Disney, British Telecom, SAP, Wind River, Motorola, Epic Games
  

A number of public Wiki sites also use TWiki

• Examples:
  https://twiki.cern.ch/twiki/bin/view/
  http://csci.mrs.umn.edu/twiki/view

Slide 4: TWiki Features

• TWiki pages are fully revision controlled, so a record of every change to every page is kept

  r6 < r5 < r4

• The look-and-feel is highly configurable, through use of templates

A "plugins" interface eases customisation extension application integration

Slide 5: Applications of basic TWiki

• A whiteboard
• A document repository
• A collaborative authoring environment
• A notebook / scrapbook
• A chat room

Slide 6: Extended applications

• A Content Management System (CMS) for websites
• A presentation development tool
• A Blog
• A database
• A project management system
• A tracking tool
• (truth is, we don't really know its limits!)

Slide 7: Structure of a TWiki page

• A header
• A body
• A footer

• The header and the footer are generated by the system
• The body contains the text of the page, as entered by you

Slide 8: The Page Header

	MyCo.MyTopic	Webs: Myco | Main | TWiki | Sandbox
	Changes | Index | Search | Go

• Changes - gives you a list of recent changes
• Index - gives you a full index
• Search - takes you to a search page, where you can search all the text
• Go - lets you type in the name of a page you already know

Slide 9: The Page Header ... continued

	MyCo.MyTopic	Webs: Myco | Main | TWiki | Sandbox
	Changes | Index | Search | Go

• For example, we might have a web called "Enemies", where we keep all we know about our enemies, and another called "Friends"
• There's usually a safe play web called something like "Sandbox" or "Scratch", where you can create pages just to try things out

The Page Footer

• The Edit link takes you to an interactive page where you can change the page content
• The Attach link lets you attach files
• The other links invoke other, more complex, functions, mainly to do with revision tracking - they can safely be ignored for now

Editing Pages

• You've read a page, and you disagree with it violently! It says:
  Everyone knows that the world is an OblateSpheroid
  But you know for a fact it is flat!
• You've clicked the edit link, and an edit page has appeared. But it doesn't look much like what was on the page before - it's full of strange hieroglyphics!

• Now what?

What's in a page

• The hieroglyphics are what's known as "TWiki Markup" or "formatting"
• They are a really simple way of telling the browser how you want the page to look
• You don't have to use them
  • TWiki understands pages in plain text just fine.
    
    Actually it is perfectly and absolutely flat
    
    appears as
    
    Actually it is perfectly and absolutely flat

Formatting just makes pages prettier

• The best thing to do is just to type until you get stuck
  • then follow the link on the edit page to the help.

Commonly used formatting

• ---+ indicates a heading. Add more +'s for a deeper heading.

  You type	You see
  ---+ This is a heading	This is a heading
  ---++ And so is this	And so is this

• %TOC% will insert a table of contents
  

More common formatting

• A blank line gives a paragraph break
  
• --- on a line of its own gives a horizontal bar
• Text in stars *like this* looks like this
  
• Text in underscores _like this_ looks like this
  
• Text in equals signs =like this= looks like this
  
• Bulleted lists use three spaces followed by an asterisk (*) at the start of the line
  • The depth of the bullet is given by the number of spaces, in multiples of three

• Numbered lists use a number in place of the *. The list is numbered automatically, so you can just use a 1

Even more.....

• You can create a table using vertical bars:

     | Cat | Feline |
     | Bear | Ursine |

• appears as

  Cat	Feline
  Bear	Ursine

• %RED% .... %ENDCOLOR% will change the colour of the enclosed text. Lots of colours are available (%RED%, %GREEN%, %BLUE% etc)

WikiWords

• One special hieroglyph that is very important is a BumpyWord
  • a word that starts with uppercase, then some lowercase, then more uppercase (a.k.a CamelCase)
• This has a special meaning to TWiki; if it matches the name of another topic, TWiki will automatically create a link to that page for you.
• If there is no such page, then the word is highlighted and a question mark is put after the word, LikeThis
• If you click on the question mark, then TWiki will invite you to create that page.

• This lets you enter the names of topics you think should exist, but don't yet
  • You, or someone else, can always come along later and click on the question mark!

Referencing other pages and URLs

• BumpyWords automatically link to the target page
  • You can make these links easier to read using square brackets:
    • [[BumpyWords][bumpy words]] appears as bumpy words
• An ordinary URL pasted into text will appear as a link - http://www.google.com
  • You can also prettify URLs using square brackets:
    • [[http://www.google.com/][Google]] appears as Google

More formatting

• If you are a real masochist, you can even enter raw HTML tags!
• Important to disable unwanted formatting, use <nop>
  • <nop>_word_ appears as _word_

Slide 1: Creating new pages

• Alternative ways:
  • Click on the question mark after a BumpyWord
  • Type in the name of the topic in the "Go:" box
  • Type in the name of the topic in the URL
• Any time you try to visit a page that doesn't exist, TWiki will invite you to create it.
• Make sure the names of topics are always BumpyWords.

Slide 2: Attachments

• Attachments are files which have been uploaded and attached to a TWiki page using the 'Attach' function in the footer.

Attachment	Action	Size	Date	Who	Comment
myco.gif	manage	9.6 K	13 Feb 2004 - 18:41	MushroomMagicMan	Attached image file

• Attachments are simply files, in whatever format you want.
• TWiki recognises some file formats, notably image files (.gif)
  • Write %ATTACHURL%/myco.gif to see this:

Slide 3: Wiki Culture

• What can I edit?
  • Anything. But it's good etiquette to sign your contributions
  • If someone doesn't want you to edit a page, it's up to them to say so, clearly, on the page
• But what if somebody doesn't like my edits?
  • In TWiki, they can always recover the old revision and re-instantiate it if they really want to

• If you click on the question mark, then TWiki will invite you to create that page.

• This lets you enter the names of topics you think should exist, but don't yet
  • You, or someone else, can always come along later and click on the question mark!

Referencing other pages and URLs

• BumpyWords automatically link to the target page
  • You can make these links easier to read using square brackets:
    • [[BumpyWords][bumpy words]] appears as bumpy words
• An ordinary URL pasted into text will appear as a link - http://www.google.com
  • You can also prettify URLs using square brackets:

• Use %SEARCH. This is an interface to a sophisticated search engine that embeds the results of the search in your page. See TWikiVariables for full details.

More formatting

• There's lots more formatting available, see TextFormattingRules and TextFormattingFAQ
• If you are a real masochist, you can even enter raw HTML tags!
• Important to disable unwanted formatting, use <nop>
  • <nop>_word_ appears as _word_

Creating new pages

• Alternative ways:
  • Click on the question mark after a BumpyWord
  • Type in the name of the topic in the "Go:" box
  • Type in the name of the topic in the URL
• Any time you try to visit a page that doesn't exist, TWiki will invite you to create it.
• Make sure the names of topics are always BumpyWords.

Attachments

• Attachments are files which have been uploaded and attached to a TWiki page using the 'Attach' function in the footer.

Attachment	Action	Size	Date	Who	Comment
myco.gif	manage	9.6 K	13 Feb 2004 - 18:41	MushroomMagicMan	Attached image file

• Attachments are simply files, in whatever format you want.
• TWiki recognises some file formats, notably image files (.gif)

Wiki Culture

• What can I edit?
  • Anything. But it's good etiquette to sign your contributions
  • If someone doesn't want you to edit a page, it's up to them to say so, clearly, on the page
• But what if somebody doesn't like my edits?
  • In TWiki, they can always recover the old revision and re-instantiate it if they really want to
  • Otherwise they should regard your changes as an opportunity for discussion
• Pages in wiki are (usually) in one of three "modes"
  • DocumentMode
  • ThreadMode
  • StructuredMode

DocumentMode

• A page in DocumentMode usually comprises a contribution which is written in the third person and left unsigned.
• The piece of text is community property
  • It may have multiple and changing authors as it is updated to reflect the community consensus.

ThreadMode

• Thread mode is a form of discussion where the community holds a conversation
• The discussion usually starts out with a statement, at the top of the page, that is subsequently discussed
• The page may be periodically "refactored" (edited) to remove some of the comments
  • As long as the comment is accurately reflected in what replaces it, nobody usually minds.
  • Remember to always maintain a complete list of contributors, though!

• ThreadMode is rather like an e-mail thread
  • Except that new comments are usually added to the end
• ThreadMode pages often get refactored into DocumentMode

StructuredMode

• A page in StructuredMode follows some predefined structure for example
  • An agenda
  • A set of meeting minutes
  • A requirement description.
• Pages in StructuredMode will usually have rules governing how they are edited.

Other Wiki tricks - Categories

• A Wiki trick for grouping pages together
• Example: to group together a set of pages all relating to the weather:
  1. Create a page called 'CategoryWeather'

• • • %SEARCH{"CategoryWeather" nosearch="on" nosummary="on"}%
  1. Put the BumpyWord 'CategoryWeather' on all the pages relating to the weather
     (usually at the bottom, below a horizontal bar)

Slide 1: A Taste of TWiki

A Wiki is like a normal web site, except that you can edit the content in your browser

"Wiki" is short for "wiki wiki", the Hawaiian for "Quick" The idea originates from Macintosh Hypercard, via Ward Cunningham In Ward's words, Wiki is "the simplest online database that could possibly work" A Wiki is basically a shared, online, persistant whiteboard

Slide 2: TWiki Wiki

Anyone can add content ... or change what is written ... or change the organisation of the content Whatever what you write is ... nicely presented ... remembered... and never forgotten

TWiki is an Open-Source development on TWiki.org

• led by TWiki:Main.PeterThoeny
• with over 100 regular contributors in many countries

Slide 3: Where is it used?

• TWiki is mainly used in commercial environments, often on corporate intranets
  • Examples: Disney, SAP, British Telecom, Wind River, Motorola, Epic Games
• A number of public Wiki sites also use TWiki
  • Examples:
    http://www.trommetter.com/cgi-bin/view.cgi/
    http://csci.mrs.umn.edu/twiki/view
    

Slide 4: TWiki Features

• TWiki pages are fully revision controlled, so a record of every change to every page is kept

  r1.6 > r1.5 > r1.4

• The look-and-feel is highly configurable, through use of templates

A "plugins" interface eases customisation extension application integration

Slide 5: Applications of basic TWiki

• A whiteboard
• A document repository
• A collaborative authoring environment
• A notebook / scrapbook
• A chat room

Slide 6: Extended applications

• A Content Management System (CMS) for websites
• A presentation development tool
• A Blog
• A database
• A project management system
• A tracking tool

Structure of a TWiki page

• A header
• A body
• A footer

• The header and the footer are generated by the system
• The body contains the text of the page, as entered by you

The Page Header

	MyCo.MyTopic	Webs: Myco | Main | TWiki | Sandbox
	Changes | Index | Search | Go

• Changes - gives you a list of recent changes
• Index - gives you a full index
• Search - takes you to a search page, where you can search all the text
• Go - lets you type in the name of a page you already know

The Page Header

	MyCo.MyTopic	Webs: Myco | Main | TWiki | Sandbox
	Changes | Index | Search | Go

• For example, we might have a web called "Enemies", where we keep all we know about our enemies, and another called "Friends"
• There's usually a safe play web called something like "Sandbox" or "Scratch", where you can create pages just to try things out
• And some admin areas, like "Main" and "TWiki"

The Page Footer

• The Edit link takes you to an interactive page where you can change the page content
• The Attach link lets you attach files
• The other links invoke other, more complex, functions, mainly to do with revision tracking - they can safely be ignored for now

Editing Pages

• You've read a page, and you disagree with it violently! It says:
  Everyone knows that the world is an OblateSpheroid
  But you know for a fact it is flat!
• You've clicked the edit link, and an edit page has appeared. But it doesn't look much like what was on the page before - it's full of strange hieroglyphics!

• Now what?

What's in a page

• The hieroglyphics are what's known as "TWiki Markup" or "formatting"
• They are a really simple way of telling the browser how you want the page to look
• You don't have to use them
  • TWiki understands pages in plain text just fine.
    
    Actually it is perfectly and absolutely flat
    
    appears as
    
    Actually it is perfectly and absolutely flat

Formatting just makes pages prettier

• A full description of all the formatting can be found in the TextFormattingRules and TextFormattingFAQ
• The best thing to do is just to type until you get stuck
  • then follow the link on the edit page to the help.

Commonly used formatting

• ---+ indicates a heading. Add more +'s for a deeper heading.

  You type	You see
  ---+ This is a heading	This is a heading
  ---++ And so is this	And so is this

• %TOC% will insert a table of contents
  

More common formatting

• A blank line gives a paragraph break
  

• Text in stars *like this* looks like this
  
• Text in underscores _like this_ looks like this
  
• Text in equals signs =like this= looks like this
  
• Bulleted lists use three spaces followed by an asterisk (*) at the start of the line
  • The depth of the bullet is given by the number of spaces, in multiples of three

• Numbered lists use a number in place of the *. The list is numbered automatically, so you can just use a 1

Slide 1: Even more.....

• You can create a table using vertical bars:

     | Cat | Feline |
     | Bear | Ursine |
     | Wolf | Vulpine |

• appears as

  Cat	Feline
  Bear	Ursine
  Wolf	Vulpine

• %RED% .... %ENDCOLOR% will change the colour of the enclosed text. Lots of colours are available (%RED%, %GREEN%, %BLUE% etc)

WikiWords"> Slide 2: WikiWords

• One special hieroglyph that is very important is a BumpyWord
  • a word that starts with uppercase, then some lowercase, then more uppercase (a.k.a CamelCase)
• This has a special meaning to TWiki; if it matches the name of another topic, TWiki will automatically create a link to that page for you.
• If there is no such page, then the word is highlighted and a question mark is put after the word, LikeThis
• If you click on the question mark, then TWiki will invite you to create that page.

• This lets you enter the names of topics you think should exist, but don't yet
  • You, or someone else, can always come along later and click on the question mark!

• An ordinary URL pasted into text will appear as a link - http://www.google.com
  • You can also prettify URLs using square brackets:
    • [[http://www..google.com][google]] appears as google
• Use %SEARCH. This is an interface to a sophisticated search engine that embeds the results of the search in your page. See TWikiVariables for full details.

Slide 4: More formatting
