Excel 2003

Sorry if this is a repeat post. Google Groups seems to take posts
about 2/3 of the time. Anyway...

It appears that Application.OnKey can do only the three following
tasks:
- Remove the assignment of an Excel keyboard shortcut.
- Restore that assignment.
- Assign a keyboard shortcut to a **MACRO**.

Can it also be used to assign a customized keyboard shortcut to an
ordinary Excel feature? For example, I'd like to assign F3 to "Find
Next" (whose default shortcut is Shift-F4; I often end up hitting Ctrl-
F4 and closing the workbook). I'd lose the existing functionality of
F3, but I never use it anyway.

If not OnKey, is there another VBA Method that would do this?

Thanks.
