One thing I do constantly with my keyboard is to hit "W" for Return-to-Zero  
Unfortunately I can't do that while using the Keyboard Virtual Controller.  
 
Seeing as how it no longer blocks "R" (Thank you!!) it would be nice if you could think of some way of dealing with "W"  
Perhaps give us an alternate shortcut for RTZ?   This would be very useful.
 
I use the alphabetical virtual controller constantly as a way of changing articulations on virtual instruments.  
 
Thank you!
