I went back to searching the forums and found Dwight's way:
I
use <name for tasks I am giving someone else and >name for tasks someone
is giving me.
I like that symbol and in thinking about it, I might double it to <<Henry and >>Henry so that a search on just < would include the math symbol 3<9. So << would not give that result. Plus, a search on << would result in every name.
<<Henry_Smith
<<Henry_Adams
etc.
l look forward to your suggestions.
