50G Solver - Use softkeys?

[MattGreer]

What is the "Keycode"? How is it used? I searched through the manual and didn't see a reference to it.

Since I have two experts seeing this thread... separate question. As I mentioned I made some little simple programs on my 48. I would very happily re-type them, they're short, into a text editor to save them on an SD card to import into the 50G, but I'm seeing that it's not that straightforward. I wouldn't mind just being able to send text straight into the calculator. But then a command like OBJ->, I assume, would translate directly.

Is Debug4x the correct answer here? It seems like, well, overkill, for the simple text transfer I'd like to do.
