Toggle between edit/extrude

I’ve searched in the Hotkey-list, and browsed the mighty internetz. But so far have not found a way to toggle on-the-fly between extrude and edit mode when in “geometry edititing”. Is there a beautiful solution to this?

hello. do u want to know how to switch between the editing mode and geometry mode ? or what are you trying to do ?

When I work with BSP geometry, I would like to get into and out of “extrude” mode by pressing a shor
tcut/hotkey.
