Variables
From Help:Magic words. These all take an optional parameter to operate on a page other than the current one. Append an "E" for equivalents encoded for use in MediaWiki URLs (e.g PAGENAMEE, NAMESPACEE).

These do not take a parameter:

Parser functions
From Help:Magic words. These are fully documented at the Meta magic words page or ParserFunctions Extension documentation unless otherwise stated. (arg0) is the arg after the colon, before the pipe before (arg1).

Metadata
Add R (i.e. =R) to return numbers without commas.

Conditional expressions
These are covered at the extension documentation page. Some parameters are optional.

Note that with  expressions, a variable like   always requires a final pipe:. If it is absent, then whenever the parameter 1 is absent, instead of leaving the field blank the software will use the actual text   and the field will never be empty.

For the use of these functions in tables, see Conditional tables.
