Hi Bob,

You can change any shortcut key at any time via Tools > Customize > Keyboard
(button)

If your macro is not in normal.dot, select your document from the "save
macros in" dropdown at the bottom (the document containing the macro must be
the active document for it to appear in the list)

Scroll down the categories list on the left and select "Macros"

Scroll down the macros list on the right to find your macro - note that it
may be qualified by module and, if need be, project so that it is unique -
and select it.

Click on the shortcut key and press Remove
Click in the "new shortcut key", press your new shortcut keys and then click
on Add.

Enjoy,
Tony
