Use two adjacent letters for keystrokes to compress with one finger
If you put 2 adjacent keys into keystrokes it makes it possible for one finger to press two keys with one finger. Group command uses Option and Command and these are side by side and one finger can quickly compress them.
And allow users to make customs keystrokes to fit the special needs of the user.
Align has no sh shortcuts. You could put Command AL to align all images to the left. Command AR, Command AB, Command AT, Command AM, Command AC Command ADH Command ADV. It would be very nice to create customized keystrokes easily. Photoshop allows great customization
