Do you mean that you want to be able to have a keyboard key or a midi cc that will basically act as a page-next and page-previous control?
If I could map four CCs I would like there to be a "Navigate-Sub-Next", and "Navigate-Sub-Previous". If I'm on the first oscillator tab on the SYNTH main-tab, then "sub-next" should tab me among the oscillators on the Synth main-tab.
The others would be "Navigate-TopLevel-Next" and "Navigate-TopLevel-Previous" taht would take me between Synth, Fx, and SEQ.
With four buttons on my beatstep I could observe all the various MAIN UI pages without using my mouse.
If I could have all of that happen when I hit the "TAB" (navigate-sub-next) and Shift+Tab (navigate-sub-prev) key on my keyboard as well, changing pages, and then Ctrl+Tab, and Ctrl+Shift-Tab for the top level tabs.
