I am trying to use tmux more than screen, but a cheat sheet could be usefull.
detach from window
ctrl-b d
list sessions
tmux ls
connect to session
tmux at -t
create session
tmux new -s "session_name" "command"
create detached sessioni
tmux new -d
split horizontal ====
ctrl-b "
split vertical ||
ctrl-b %
move to other pane
ctrl-b cursor-key-direction
move to other pane using numbers
ctrl-b q + number of pane you want to go (when you type q yo see the number of the panes)
rotate panes
ctrl-b ctrl-o
reverse rotate panes
ctrl-b ctrl-alt-o
create new window
ctrl-b c
go to specific window
ctrl-b 0 t/m 9
go to next window (tab)
ctrl-b n
go to previous window
ctrl-b p
ctrl-b :set -g mouse on|off
or add it to ~/.tmux.conf
type in all windows
ctrl-b :setw synchronize-panes on
type in all windows off
