paint all tool

Ok, so I’m working through the tutorial and the painting section tells me that I can [shift]+[option] on the Mac to get the paint all tool to paint multiple exposures at once. Unfortunately, nothing happened. Am I missing something? Come to think of it I also had trouble getting the rotating light table to work as well. Are the problems related? They both require keyboard shortcuts.


Not sure but if your option key does not trigger properly you may have difficulties using both the paint all and the rotating light table. Have you ever encountered difficulties using this specific key on your keyboard before?
