I was just fooling around with keyboard shortcuts and tried assigning option-P as a shortcut for inserting paragraph tags. The shortcut is assigned successfully (it shows up in the window and pop-up menu item fine), but then pressing option-P in the editor doesn't trigger the macro, it just prints the pi character like option-P normally does. After trying several variations, it appears that the macro will only trigger if the command key is included as part of the shortcut.
So, it would seem that the proper behavior should either be a) for the macro shortcut to work with whatever key combo you typed in, or b) if the command key is required to be there, then the user shouldn't be able to enter a shortcut that doesn't have the command key as part of it (or maybe the command key should be added automatically).
Do other people get this same behavior, or am I special? :)
