Zoom in or out on piano roll editor - MacOS
I recently discovered how to get most of the Timeline features to work with MacOS - using a scroll wheel mouse.
The Piano Roll Editor (PRE) looks in some ways similar, but all I've managed to do so far is to zoom in vertically. I'd like to be able to make the PRE narrower or wider, but can't find a way. I looked for shortcuts to see if that would give me a clue. It did, but the shortcuts didn't work.
Is it possible to zoom in and out horizontally with this editor tool?
