I'd like to change my tmux prefix key from control to command (on mac).
I have an example on how to set it to alt:
set-option -g prefix M-b

@NickODell I looked there, but noone talks about just setting the option– foreyezJul 4, 2018 at 18:16

tmux supports Alt+key (Meta+key) by prefixing the key with M-, or Ctrl+key with the C- prefix in the key binding specification. There is no support for any other modifier keys.
Related question on the SuperUser site: bind tmux prefix to OS X cmd key (or any other binding)
Also this random Reddit post: tmux on OS X: how to use the Cmd key with bind?
The general gist of these posts is to rebind a macOS command key sequence with some other software to send an Alt or Ctrl key sequence to tmux.

2for some reason alt didn't work for me. ended up mapping the prefix to control-space on my mac. "set-option -g prefix C-Space"– foreyezJul 4, 2018 at 18:28
