I have recently moved from Windowns to Mac and am getting used to the new layout.
One of the most useful key commands I had was clicking the ? Key and all the tracks conforming to a default size. Very useful after resizing for editing.
On the Mac the same command doesn’t work and I cant find the name of the function to create my own.
here’s an overview how to get there - you have got a variety of options.
I find it quite useful to assign a key command to a dedicated track height like 2 rows to restore all changes at once. You find all related key commands under Edit/ key commands / Zoom > …track height
If you are working with a split window in the Project Window these commands will only apply to tracks that reside in the same half as the currently selected track.
