The Basics of Scrolling in Tmux<\/h2>\n

Using the Mouse<\/h3>\n

If you’re using a graphical terminal emulator, you can use your mouse to scroll through your Tmux output.

From here, you can use the arrow keys to scroll through your output. To exit copy mode, simply press the q<\/code> key.<\/p>\n

Copy Mode<\/h3>\n
