			Find out how much is left on a timed variable (set with -u switch)
			;set a variable, that will be unset in 2 minutes
			[[set]] -u120 %i Test

			;Later you can use this:
			[[echo]] -ag $var(%i,1).secs

Returns information about currently set [[:Category:Variables|variables]], [[Local Variables|local]] or [[set]].

$var(variable name [,N])[.value|.local]

* Variable name is a wild card value.
* N tells us we want the Nth matching variable.
** N is 0 by default, and therefore can be used to check for existence without it
* Returns
** Variable name by default
** Value if .value is specified
** If .local is specified, returns [[$true]] or [[$false]] based on whether or not the matching variable is a [[Local Variables|local variable]]
