I would like to add superscript/italics to a very small portion of the words
in one single text cell, but not for the entire cell. How can i select the
option to add formatting changes to one or two words from the text in the
cell, without having to change it for everything in that cell?

When I highlight the part of the cell I want to reformat, I won't have the
option to enter into formatting. I have to select the entire cell before the
option 'format cells' become available.

Is there any way I could figure this out? Thanks for your help!
