Keyboard shortcuts for sub-sub-menu items?

Hi,

I'd like to make a keyboard shortcut for Keynote's "Format > Font > Baseline > Raise" menu command. The Help menu says that the menu command must be typed in precisely as it shows up in the menu, but says nothing of how to specify the submenu hierarchy. (And, it seems to be needed, since entering just "Raise" does nothing.) The real pain in this is that one must quit the application and restart it for the keyboard shortcut to "take". So, although there is "only" a finite number of possible key-combinations to try, I'd rather ask if anyone happens to know the correct way to enter this.

Thanks, Tristan
