I am guessing that if you press command-option-8 once (on Panther),
command-option-minus in Word will stop working. This is because it's in
use as a system-level hot key. See the Universal Access pref pane. m.
Thanks! I've never used that shortcut before. It may come in very useful
(I'm helping some of my website clients to become compliant with
accessibility standards).
This seems like an Apple bug to me - unless the CMD-OPT-<minus> shortcut
is forbidden to OSX applications, there should be some indication,
preferably on the screen, when the UA shortcuts are in effect. As it is
now, it's entirely possible to inadvertently hit CMD-OPT-8 and lose
control of other shortcuts.
