Macros are suspended when in Edit mode, so a custom button wont' work.

You may want to look at John Walkenbach's SuperSub add-in, which makes
super/sub-scripting a bit easier:

I would like to create a custom button in XL2k to format the selected
text as subscript, superscript, etc. It would function just like the
built-in buttons in Word. That is, I could select a portion of the
text in a cell's string, hit the button and the selected portion would
be formatted. As is, when I select a portion of the string the macro
menu options are greyed out. I note that the copy and paste buttons
don't grey out. Has anyone found a work around?
