how to add a bar on top of a character in Word?

[alid]

I'm trying to type up an equation where I need to add a bar on top of a
character (in other words, upperline a character) in Word. Is there a way or
show I use a different editor which will allow me to do so.

Bravo! Thank you for helping me out. I guess I just didn't look hard enough
for the answer and didn't use the right word to search. Again, thank you so
very much.
