TWiki Variables

Most predefined variables return values that were either set in the configuration when TWiki was installed, or taken from server info (such as current username, or date and time). Some, like %SEARCH%, are powerful and general tools.

Predefined variables can be overridden by preferences variables

Predefined variables can be overridden by preferences variables (except TOPIC and WEB)

Plugins may extend the set of predefined variables (see individual Plugins topics for details)
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 %INCLUDINGTOPIC%, %INCLUDE%, and the mighty %SEARCH%.
