tmux cheat sheet

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

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

	#include <stdlib.h>
	#include <stdio.h>
	#include <stdint.h>
	#include <fcntl.h>
	#include <sys/stat.h>
	#include <sys/mman.h>
	#include <unistd.h>

	int main(int argc, const char *argv[])
	{
