Why, thank you.

Here's another curious observation (tee hee):

When I try to assign the Word macro to f11 by pressing that key in the
"select shortcut key" dialogue box - up comes "f11". So the key *is* being
recognised.

I tried reassigning it with different things: letters, symbols - and none of
them worked either.

I confess myself puzzled.
