	Tips for using Tmux more efficiently

	### Enter in copy mode

	By default Tmux uses the emacs key-bindings, to make a selection you
	need to enter in `copy-mode` by pressing Ctrl+b and then [ with Ctrl+b
	being the tmux prefix key, if you changed it then do the replacement
	while reading.

	If you need to quit the copy-mode, type Ctrl+C.


	### Make a selection

	While in copy-mode, selects your start or ending position for your
	selection and then press Ctrl+Space to start the selection. Now, move
	your cursor to select the text and press Ctrl+w to validate.


	### Paste a selection

	When you want to paste your selection, press Ctrl+b ] (you should not
	be in copy-mode for this!).


	### Make a rectangular selection

	If you want to make a rectangular selection, press Ctrl+space to
	start and immediately, press R (capitalized R), then move your cursor
	and validate with Ctrl+w.


	### Output the buffer to X buffer

	Make a selection to put the content in tmux buffer, then type

	tmux save-buffer - \| xclip

	You may want to look at xclip (it's a package) man page.

	### Output the buffer to a file

	tmux save-buffer file

	### Load a file into buffer

	It's possible to load the content of a file inside the buffer for
	pasting it somewhere.

	tmux load-buffer file


	You can also load into the buffer the output of a command, using a
	pipe and - as a file like in this example:

	echo 'something very interesting' \| tmux load-buffer -


	### Display the battery percentage in the status bar

	If you want to display your battery percentage and update it every
	40 seconds, you can add two following lines in `~/.tmux.conf`:

	set status-interval 40
	set -g status-right "#[fg=colour155]#(apm -l)%% \| #[fg=colour45]%d
	%b %R"

	This example works on OpenBSD using apm command. You can reuse
	this example to display others informations.
