I have recorded a macro, but it only seems to run on the worksheet that it
was created on. I would like to (1) record/save a macro will be available to
all Excel files/worksheets, (2) assign the macro to a custom button, and (3)
add that custom button to the end of the formatting toolbar. As mentioned, I
would like this macro button to remain in the toolbar no matter what
spreadsheet that I'm working with. How can I accomplish this?
