5.5.2-Audio Part Editor-Horizontal Scrolling

Hi All :
I’m attempting to program a new Bella Keyboard with scroll/jog wheels to control Cubase. I do a ton of audio editing and I’m hoping that this will help speed things up.

Finding most of the key commands and programming them to the keyboard are straight forward, but, within the Audio Part Editor, the “horizontal locator bar” at the bottom of the Audio Part Editor window has no key command associated with it that I can find.

I want to be able to use the jog wheel to jog left or right, little by little, not in giant leaps within the audio part editor window.

Can anyone help ?
