Keyboard shortcut behavior Kinda solved

I've used the ctrl+/- forever on my qwerty. I am on touch now. I put the custom module handy and put the 2 commands Zoom current track in/out - vertical in 2 slots to save constantly grabbing for the keyboard. But, it doesn't do anything in either direction. Neither does the 'all tracks version of these commands. It hasn't mattered if I have auto track zoom on or not. I'm looking to be able to toggle that state back and forth. Am I missing something? Thanks, Shep 
 
Oddly, the Zoom In/Out Horizontally works well...
 
By chance would I have to unbind them? They are of the 'hardwired from the factory' variety, if you will.
 
As it turns out, you can't hold the touch screen down and rapidly change the view. It's a small amount of change per tap. It works, but not the way the keyboard does. Bummer. More patience needed - anybody got some I can use?!?
