Volume control shortcut.

Hello,
it seems to me that a keyboard shortcut for moving the volume control is missing, at least into the evaluation version.
So, unless this option escaped to my attention, I'm wondering if you could add this keyboard shortcut to the ones already available, for example by leaving as defaults the "shift+" and "shift-" to enlarging/shrink the user interface and using the "+" and "-" for the volume control.

Sincerely.
