I'm not aware of any documented shortcut in Excel for Ctrl+Alt+Arrow Down.
That shortcut will dim the screen in Windows and Ctrl+Alt+Arrow Up will
brighten the screen up to the limit.

I would assume you assigned your own shortcut key to a macro.

BTW the use of Ctrl+A can get you into serious trouble in Excel 2003.

What did the shortcut do for you?
[in other words what does it do instead of work?]

Perhaps you are thinking about Ctrl+Shift+Arrow Down which extends the selection.

Just upgraded to Excel 2003 and none of the keyboard shortcut keys work.
(example: Alt-Clt Arrow Down does nothing) Is there a setting that needs to
be changed?
