Cubase 9 - how to program a fixed zoom?

Hi there…
Is there a way to program a shortcut to zoom to specific range back and forth, instead of pressing G or H several times? It would help in the editing process …

Thanks and regards

I have 4 key commands for 4 fixed zooms: 1 bar, 2 bars, 4,bars and 8 bars. Is that what you mean by fixed? If so yes, it’s in key commands. You determine the bar length.

Yes, that’s what I meant. Thanks a lot ¡
