MQ: Implement keyboard shortcuts for some patch queue actions (Apply/Unapply one patch, Unapply all patches)
Using MQ (Patch Queue) would be so much more efficient with keyboard shortcuts!
I suggest the following contextual shortcuts (with focus in Patch Queue widget):
Ctrl++ (Ctrl+Plus): Apply one patch Ctrl+- (Ctrl+Minus): Unapply one patch Ctrl+Shift+Enter: Unapply all patches
This is consistent with option 3 of my proposal in #5509:
Shift+Enter: *Unapply up to this patch* Enter: Go to patch (*Apply up to this patch*, existing keyboard shortcut)
