Yes, I mentioned in another comment that I only brought up Kitty for diplomatic reasons (which was weird of me, lol). I don't really know anything about Kitty other than it's often brought up as an alternative to Alacritty. I should have just left it at Alacritty!

I use kitty locally and only usr tmux on remote servers where I would not like to lose my session.

Running remote tmux inside a local tmux is just to error prone and forces you to remember different bindings.

There is an approach to use tmux inside tmux without using different set of keybindings. That's what I have been using for couple years and I really like the setup. I have the following binding in my local machine:

    bind -T root F3 \
      set prefix None \;\
      set key-table off \;\
      set status-left '#[bg=#C678DD,fg=#2C323C](pass-#S)' \;\
      set status-style bg=#E06C75 \;\
      set window-status-current-style bg=magenta,fg=black \;\
      refresh-client -S;

    bind -T off F3 \
      set -u prefix \;\
      set -u key-table \;\
      set -u status-left \;\
      set -u status-style \;\
      set -u window-status-current-style \;\
      refresh-client -S;

This way, pressing F3 in local machine disables the prefix and I can use remote tmux as if it is local. When I want to get to local tmux, I press F3 once and I am back to local tmux. I use highlighting to easily show that local prefix is disabled.

Thanks, this is excellent!

Reading more about Kitty now is peaking my interest. I feel like there is a reason I ignored Kitty in the past but I can't remember.

Piquing, not peaking :)

lol, yes, thanks :)

For me it was the excessively minimal defaults. I also forget the exact issues, but I remember Alacrity felt usable even before editing the conf file; Kitty didn't.

The author has a hatred of bitmap fonts for some reason.

I've been using kitty for 3 years now and I love how fast it is. It's the first time I read of other people using it. At my job nobody knows of it.
