Thanks, Bert - I do want to keep that scroll wheel behaviour, and
re-routing the scroll events to do what the key combination did and
then changing the key combination is a bit too awkward and probably
more trouble than it's worth. Guess I'll try to override one of the
other key combinations and map it to a mouse gesture shortcut instead.

I'm still curious, though, as to why the cursorUp: and cursorDown:
methods seem to be assigned to the Cmd shortcuts, yet are only called
(judging from when they hit an inserted halt) when the arrows are
pressed without Cmd keys...
