There are three tmux customisations that I love and use all day: 1. Set the prefix key to C-Space. Much easier to type then any letter, and (in my case) only collides with Emacs set-mark. Its easy to remember and just type C-Space C-Space in that case. 2. Set IC (insert key) as prefix2. If you have a full-size keyboard, you can now scroll up by pressing insert (on the block of 6) and pageup. Easy to type. 3. Using sessions for ssh hosts. Add ControlPersist and/or AddKeysToAgent to ~/.config/ssh and bind the following to some key. Pressing that key will prompt for a hostname, and create a new session named after that hostname. The default-command will make it such that Prefix c will open a new window which is already logged in on that host. Its not the same as running a remote tmux, as your windows/session will not persist on the remote host, but it avoids nested tmux. I use it all the time during a typical day... command-prompt -p "Secure Shell ([user@]host):" { new-session -A -s "%1" "ssh %1" ; set-option default-command "ssh %1" }
