The "macro-list" macro generates a complete list of the macros enabled on this wiki. Enter this macro in wiki markup. The syntax is:
{macro-list}
The list is not displayed, because the output is not Section 508 compliant.
The macro browser that opens when you type Ctrl-Shift-A and each time you type the first few characters of the name of a macro also displays a list of macros enabled on this wiki.
