tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

It is possible to redirect some input to TTY device by standard IO redirection.

echo ahoj > /dev/tty1

Such redirection will however end in the output buffer of the TTY device so the characters will be ghosts - visible on the terminal, but not effective. It is, in fact, not possible by standard tools to redirect input to terminal as if it is a real input from keyboard.
