It is easy to collaborate; just type your text. You don't need to know HTML at all, though you can use it if you prefer. Links to topics will be created automatically, as long as you follow these simple Text Formatting Rules. TextFormattingFAQ has answers to frequently asked questions about text formatting. This page is available in a pop-up window when in Edit mode.

---++ Links

Being able to create links without any formating required is a core TWiki feature, made possible using WikiNames. With the latest version of TWiki linking rules, by adding a few extra symbols, you can have even more powerful linking control. 

---+++ %WIKITOOLNAME% Internal Links

   * GoodStyle is a WikiWord that links to the <nop>GoodStyle topic located in the current %WIKITOOLNAME% web. 
   * NotExistingYet is a topic waiting to be written. You could create that topic by clicking on the question mark. (Do not create that topic; you would wreck this example!)

---+++ Remote Site Links

   * =http://...=, =https://...=, =ftp://...= and =mailto:...@...= are linked automatically. 
   * Email addresses like =name@domain.com= are linked automatically.

 You can create a forced internal link by enclosing words in double square brackets. <br> __Note:__ Text within the brackets may contain optional spaces; the topic name is formed by capitalizing the initial letter and by removing the spaces; i.e. =[<nop>[text formatting FAQ]]= links to topic TextFormattingFAQ.

 Create a link where you can specify the link text and the link reference separately, using nested square brackets like =[<nop>[reference][text]]=.

Anchor names can be added as well, like =[<nop>[WebHome#MyAnchor][go home]]= and =[<nop>[http://www.yahoo.com/#somewhere][Yahoo!]]=.

 You can define a link reference inside a %WIKITOOLNAME% topic (called an anchor name) and link to that. To __define__ an anchor write =#AnchorName= at the beginning of a line. The anchor name must be a WikiWord. To __link to__ an anchor name use the =[<nop>[MyTopic#MyAnchor]]= syntax. You can omit the topic name if you want to link within the same topic.

---++ Using HTML

Most HTML tags will work, but it's almost always preferable not to use HTML, so that the markup remains easy for everyone to edit.

   * HTML 4.01 Reference Specification: http://www.w3.org/TR/html4/
   * Quick reference of all HTML elements: http://werbach.com/barebones/barebones.html


---++ TWiki Variables

Variables are names that are enclosed in percent signs; they get expanded on the fly.

   * =%<nop>TOC%= : The table of content, is based on headings in a topic.
   * =%<nop>WEB%= : The current web, is <b>%WEB%</b> .
   * =%<nop>TOPIC%= : The current topic name, is <b>%TOPIC%</b> .
   * =%<nop>ATTACHURL%= : The attachment URL of the current topic. Example usage: If you attach a file to a topic you can refer to it as =<b>%<nop>ATTACHURL%/image.gif</b>= to show the URL of the file or the image in your text.
   * =%<nop>INCLUDE{"SomeTopic"}%= : Server side include, includes another topic. The current %WIKITOOLNAME% web is the default web. Example: =<b>%<nop>INCLUDE{"%TWIKIWEB%.TWikiWebsTable"}%</b>= </td>
   * There are many more variables, see TWikiVariables.

---++ "Gotchas" when Editing Text

The formatting rules are fairly simple to use and fast to type. However, there are some things to watch out for:

   * *Q:* Text enclosed in angle brackets like =&lt;filename&gt;= is not displayed. How can I show it as it is?
      * *A:* The ='&lt;'= and ='&gt;'= characters have a special meaning in HTML, they define HTML tags. You need to escape them, so write ='&amp;lt;'= instead of ='&lt;'=, and ='&amp;gt;'= instead of ='&gt;'=. <br> Example: Type ='prog &amp;lt;filename&amp;gt;'= to get ='prog &lt;filename&gt;'=.

   * *Q:* Why is the ='&amp;'= character sometimes not displayed?
      * *A:* The ='&amp;'= character has a special meaning in HTML, it starts a so called character entity, i.e. ='&amp;copy;'= is the =&copy;= copyright character. You need to escape ='&amp;'= to see it as it is, so write ='&amp;amp;'= instead of ='&amp;'=. <br> Example: Type ='This &amp;amp; that'= to get ='This &amp; that'=.
