+_Special text strings expand on the fly to display user data or system info_
-TWikiVariables are text strings enclosed in percentage signs: <code>**%VARIABLE%**</code> that represent stored data. When a topic is rendered for viewing, defined variables replaced by their actual values. TWiki has two types of variable, predefined, and Preference-based, where you can change settings. Through Preference variables, you can even define custom variables. Clearly, they are a power TWiki feature.
+TWikiVariables are text strings - `%VARIABLE%` - that expand into content whenever a page is opened. When a topic is rendered for viewing, `VARIABLES` are replaced by data, either user-entered, or info automatically generated by TWiki (like the date, or the current username). There are predefined variables, and Preference variables that you configure. You can also define custom variables, with new names and values.

-%WIKITOOLNAME% expands the following variables enclosed in % percent signs:
+Most predefined variables return values that were either set in the <code>**lib/twiki.cfg**</code> file, when TWiki was installed, or taken from server info (like current username, or date and time). Many of the variables let you format the appearance of the display results.

+- %T% **Take the time to thoroughly read through ALL preference variables.** If you actively configure your site, review variables periodically. They cover a wide range of functions, and it can be easy to miss the one perfect variable for something you have in mind. For example, see <code>**%INCLUDINGTOPIC%**</code>, <code>**%INCLUDE%**</code>, and the mighty <code>**%SEARCH%**</code>.

+- You can add your own preference variables for an entire site, a single web, or a single topic, using the standard syntax. Whatever you include in your variable will be expanded on display, and treated exactly as if it had been written out. So you can place formatted text, page links, image paths.
