I have been using shortcuts in Adobe XD to increase my working speed. I use my left hand on the keyboard and right on the mouse.
Since we are using [ Shift + M ] for aligning elements in the middle, I found that it is a bit difficult to reach my left thumb to letter M while I'm holding the Shift key with my left pinkie. So it is affecting the free flow of my design.
Most of the other Shortcuts are easily accessible such as Copy, Paste, Duplicate...etc
I wish you to check this from a user perspective and find an ideal solution.
