I am seeking help in creating a custom command for a MS Excel XP toolbar.

In MS Word XP, I added a “Next Window� button to my standard toolbar, by
going to the Tools menu, selecting Customize, Commands, Window & Help & then
dragging the “Next Window� command to my toolbar. I open several documents,
then simply click on “Next Window� to go to the next open document (sort of
like scrolling between documents).

I want this same "feature" in Excel, but when I get to the Window & Help
section, there is no “Next Window� command to chose. I have tried a macro,
but can’t get it to work. My macro knowledge is minimal & I am unable to find
the actual command that will allow me to go to a next window.

Can anyone assist in creating this command or perhaps copying from MS Word?

Appreciate any assistance.
