Feature Request: Add keyboad means to zoom in Piano Roll Editor

• May 19, 2019 - 22:19

Currently, without a mouse, there appears to be 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 to have a purely keyboard way of zooming. To be consistent with the rest of app, I suggest that Piano Roll Editor adapt the same keyboard shortcuts as the rest of the app-- ctrl + for zoom in, ctrl - for zoom out, and ctrl 0 to reset zoom to 100%--and add trackpad pinch zoom. Also, I suggest adding the ability to enter the zoom level in the upper horizontal settings bar, again as you can in the regular notation view. The above suggestions would make the Piano Roll Editor more accessibility friendly.

While it's true that many if not most people are using a laptop without a mouse, the vast majority of them do have touchpads or similar devices with equivalent touch gestures for zooming (eg, pinch, or Ctrl+drag). So, not that it wouldn't be useful add another method, but to be clear, lack of a mouse in no way should prevent anyone from zooming.
