zsh users are advised to use the terminfo database as the most portable way to assign commands to particular keychords, but I haven't been able to find a database of which terminfo sigils correspond to which keys. Fortunately, I found enough information written in ancient Sumerian that I could translate it into something modern humans can comprehend.

For no adequately explained reason that I can find (wasn't the point of terminfo to smooth over historical nonsense like this?) not all combinations of modifier and function keys have names. However, if you press Ctrl-V at the commandline, then hold down Shift and Alt and hit the F4 key, you'll get something (for me it looks like ^[[1;4S) which you can use in zsh---just replace the ^[ with \e. I don't know how portable these codes are, though I'd wager they're the same on most modern systems - caveat emptor.
I confess it has been so long since I wrote this I've forgotten what I did to find things out. I may just have neglected to try Shift-Backspace.
