Use a custom format like this

"From:" @

when you type in something like "test" in the cell it will look like this

Can anyone help me figure out how to keep a "fixed" word in a cell but add
information? For instance; I have a cell that says "From:" I would like to
keep that word fixed and be able to type a date after it without having to
retype From then the date. Is there a cure? Any help would be great!
