Suggested feature: Toggle groups of hotkeys via interrupt

[morganwl]

I'm not sure if this project is still open to and accepting pull requests, but I had a feature that I plan to attempt for my own use case, and wanted to see if there was broader interest / input before attempting implementation.

I would like to be able to group hotkeys in the configuration file, and use a USR signal (with attached message) to toggle a group. My use case is integrating window navigation with vim, similar to the functionality of vim-tmux-navigator when working in a terminal. Currently, I capture the keystroke in sxhkd, and, if vim is focused, trigger a vim function, otherwise trigger a wm action. I'd like to skip the "check if vim is focused step", and allow vim to capture and handle the keystrokes directly.

The simplest implementation I have considered would be to add a boolean flag to the hotkey structure, and return NULL if a hotkey is found but marked disabled. I have also considered ungrabbing the hotkeys from xcb altogether.

Would there be broader interest? Are there any thoughts or suggestions? Thanks for your time in putting this program together!
