Multi-key shortcuts / key chords?

[ttytm]

I couldn't figure out how to use multi-key shortcuts. Skimming the issues I couldn't find something on this either. So this might be a feature request.

The goal is to map multi key shortcuts, like it's possible in e.g., tmux, kitty, vim, vscode etc. E.g. Ctrl+Wv to create a vertical split.
