# <a name="TWiki_Text_Formatting"> TWiki Text Formatting </a>

Working in TWiki is as easy as typing in text - exactly like email. You don't need to know HTML, though you can use it if you prefer. Links to topics are created automatically when you enter [[WikiWords]]. And TWiki shorthand gives you all the power of HTML with a simple coding system that takes no time to learn. It's all layed out below - refer back to this page in a pop-up window from the **Edit** screen.

## <a name="Using_HTML"> </a> Using HTML

You can use just about any HTML tag without a problem - however, to keep in mind:

* On collaboration pages, it's preferable NOT to use HTML, and to use TWiki shorthand instead - this keeps the text uncluttered and easy to edit.
  * **_NOTE:_** TWiki converts shorthand notation to XHTML 1.0 for display. To copy a fully marked-up page, simply view source in your browser and save the contents.
  * **_NOTE:_** The standard installation TWiki is compatible across a wide range of browsers and computer platforms. If this is important to you, remember that using browser-specific tags or any other mark-up that doesn't degrade well will reduce compatibility.

## <a name="Hyperlinks"> Hyperlinks </a>

Being able to create links without any formatting required is a core TWiki feature, made possible with [[WikiWords]]. New TWiki linking rules are a simple extension of the syntax that provide a new set of flexible options.

### <a name="Internal_Links"> Internal Links </a>

* [[GoodStyle]] is a [[WikiWord]] that links to the GoodStyle topic located in the current %WIKITOOLNAME% web.

* [[NotExistingYet]] is a topic waiting to be written. Create the topic by clicking on the **?**. (Try clicking, but then, **Cancel** - creating the topic would wreck this example!)

### <a name="External_Links"> External Links </a>

* `http://...`, `https://...`, `ftp://...` and `mailto:...@...` are linked automatically.

* Email addresses like `name@domain.com` are linked automatically.

* <code>[[Square bracket rules]]</code> let you easily create non-WikiWord links.

## <a name="TWikiPlugin_Formatting_Extension"> TWikiPlugin Formatting Extensions </a>

Plugins provide additional text formatting capabilities and can extend the functionality of %WIKITOOLNAME% into many other areas. For example, the optional [SpreadSheetPlugin](http://twiki.org/cgi-bin/view/Plugins/SpreadSheetPlugin) lets you create a spreadsheet with the same basic notation used in TWiki tables.

Available Plugins are located in the [Plugins](http://twiki.org/cgi-bin/view/Plugins) web on TWiki.org. Currently enabled plugins on this TWiki installation, as listed by <code>%PLUGINDESCRIPTIONS%</code>:
