~~Title: Evaluator Button Tooltips~~
<pageheader/>

You can use the evaluator to generatge the tooltip for a toolbar button dynamically.

Unlike [[icons]] and [[labels]], there's no @ modifier for tooltips - instead, you enter a `=` character followed by the evaluation expression, directly into the tooltip field in the button editor.

{{page>standard_variables&nodate&nouser&nofooter}}

The return value from the evaluation expression will be used as the tooltip for the button.
