What is a macro?
TiddlyWiki Community Wiki
A macro is a predefined function or operation that can be inserted into a tiddler contents. It is invoked whenever the tiddler is rendered normally, and typically inserts content into the rendered text at the point where it is referenced. Referencing a macro is done using the syntax:
<<macroName paramvalue1 paramvalue2>>
or with named parameters
<<macroName param1:value1 param2:'value2 with spaces'>>
There are several macros built into the TiddlyWiki core. Many additional macros are available by installing Plugins
