Keydown command modifier descriptions for tooltips

[yonder]

The ability to provide descriptions for each entry of @keydown modifier in command editor to show in tooltips.

Command editor example:

@keydown:none
Command1
@keydown:ctrl:"Run Command1a"
Command1a
@keydown:shift:"Run Command1b"
Command1b

Shows the key and description in button tooltip.

Wow, many thanks!

Looking good - alignment is out (top ones in description, bottom ones in @keydown)
