Changed Outlook Behaviror--How to Change Back?

[PlarfySoober]

Somehow, I changed Outlook so that two things are not as they were:

1. The keystrokes for "Send," <Ctrl>-<Enter>, no longer work. Nothing
happens (I suspect it was a change I made in Word to make it a little more
like WordPerfect, but I dunno); and,
2. The keystrokes for "Macro Run," <Alt>-<F8," bring up something related
to Help, instead of running a macro.

Obviously, it's a newby mistake, and I'll take that. But does anyone know
what I did, and how to reverse it?

Thanks.

Don.
