How do I bind keypresses to tmux sequences?

[joebonneau]

I have tmux keybindings that I have mapped to various utility functions, such as ctrl + b > T opens up a tmux session picker. I have this mapped to cmd + k. In Alacritty, you can map that with the following:

[[keyboard.bindings]]
chars = "\u0002T"
key = "K"
mods = "Command"

or

key_bindings:
  - { key: K, mods: Command, chars: "\x02\x54" }

I tried this in my Ghostty config with the following, which sends the final keypress (T) instead of triggering ctrl + b, then k:

keybind = cmd+k=text:\x02\x54

How do I go about doing this?

Did you try keybind = cmd+k=text:\x02t?
