Tmux becomes more awesome when you use something like Alacritty or Kitty [EDIT: scratch Kitty, this mainly applies to Alacritty] and map your system's key (Apple's command key or... whatever it would be on Linux or Windows) and use that as your "tmux key". That way you can make single-chord bindings for all things tmux and life becomes better. If you use Vim, adding VimTmuxNavigator[0] improves things so much. For example, to seemlessly switch between panes, be they tmux panes or vim panes, I use `cmd-h`, `cmh-j`, `cmd-k`, `cmd-l`.
It's possible to achieve "command as tmux key" with iTerm which I did do for years but I don't recommend it. It's very hacky.
