Do you mean specific formatting, such as bold, or the application of a
particular font or other direct formatting? Yes. Edit - Find, click More.
Use the Format button at the bottom to choose the desired formatting you're
looking for. If you leave Find what: blank, then it will look just for the
formatting, regardless of what text it's applied to.
If you mean direct formatting in a general sense, it would depend upon a
number of factors, and how to set it up would depend upon which version of
Word you're using.
