Simpler than the title makes it sound. I'm trying this:

ON KEY LABEL PGDN "UB92A."

or variations of that to try and type those characters into a program whenever I need them. I have other keys that will be used for other snippets of text. I just can't seem to figure out the right combination of INKEY or KEYBOARD or whatever to get it to work. I know it's easy, I just can't recall how to do it. Thanks!
