Feature Request: Add more means to zoom in Piano Roll Editor.

S5 - Suggestion

Currently, without a mouse, there is no way of zooming in or out in the Piano Roll Editor. Since many people use Musescore on a laptop without a mouse, it makes sense to provide other means for zooming. To be consistent with the rest of the app, I suggest that Piano Roll Editor adapt the same keyboard shortcuts-- ctrl + for zoom in, ctrl - for zoom out, and ctrl 0 to reset zoom to 100%--add trackpad pinch zoom, and the ability to enter in the zoom level in the upper horizontal settings bar. The above suggestions would make the Piano Roll Editor more accessibility and laptop friendly.

Workaround No Yes

zooming is possible even without a mouse, via a touch pad or tough screen and a pinch gesture or Ctrl+drag
And may not be (easily) available even with a mouse (if that doesn't have a scroll wheel)

I got an email about this issue. Is the workaround enough to resolve it, or does work need to be done to add the keyboard zoom options?

I think "Zooming the Piano Roll Editor" (other than the name of a movie and its character) sounds to me (a frequent patron) not like "just let me see the bits bigger" but allowing interaction with more resolution on very fast notes, which requires application participation beyond OS zooming.
