In most programs, if a menu item has a keyboard shortcut attached to it, that shortcut is printed in the menu (right aligned).
I suggest that this also be aded to comical. E.g. Go->Next Page should show the next page icon (right arrow head), followed by "Next Page", followed by "PgDn" right aligned.
mac MBP osx snowleopard, cannot find next page shortcut. If it is right arrow, it does not work.
