Great, thanks for the suggestion. Figured out how to send one to your fork as well without any extra hassle.

On my remote shell the shortcuts aren't 100% working yet with byobu. There's still some of the base function keys (F2 etc. by themselves) and certain combinations that don't do anything. This repo has definitely got some of them working that weren't before. It's set me on the right path for figuring it out eventually anyway. Thanks for making it

@Henry-E I'm using it with tmux/zsh/native macOS terminal, if that makes a difference.

I've tried my best to document all the decisions in the python source file. For each key there are many variants of encoding, try modifying the source and see if it helps. I know little about terminfo and friends and mostly googled and trying until it worked. Any input (like links to useful docs) is welcome.
