The current shortcut menu show the command on the left and the action on the right. People don’t look up an action to see what it does. Rather, they look for the action they want and its related shortcut.
I want to know, for example, how to toggle the table switcher not what CMD J does, but the current keyboard shortcut table doesn’t help find that. You have to search for the action.
That is, the left hand column should be an alfa list of actions and the right hand column the keyboard shortcut.
