Some bindings aren't working #269

Hi there,
first of all some words of appreciation - love the UI and the concept!

Just played around with toad a little and noticed that - at least for me - some bindings aren't working when running it within tmux.

Ctrl+h and Ctrl+[ wouldn't work, Ctrl+] does... I am running the latest version within ghostty. Checked with cat -v - keycodes are what to expect: ^[ ^] ^H. So tmux doesn't eat the keypresses - but apparently they still don't make it to toad.

Any idea what might be wrong?
