How I use cmd+k as my tmux prefix

Cmd + k on mac uses a thumb and a home row key. Comfortable for me!

• I use the default ctrl + b prefix in my tmux config 
• I  configure my terminal emulator to map cmd + k to send ctrl + b to the terminal

In Alacritty it's like this:

[keyboard]
bindings = [
	{key= "k", mods= "Command", chars= "\u0002"}
]

I set up with Ghostty today with this config:

keybind = cmd+k=text:\x02

If your pinky hurts, try this out!
