How do I scroll in tmux?

I just started using tmux, and I really like it, but I need to be able to scroll within the buffers/panes/windows I have open. I don’t care if it works with the mouse or not. When I search the tmux man page, I find only two instances of the word “scroll” even showing up, and both have to do with copy mode. Is there a way to scroll without all the overhead of entering copy mode?

Answer

Ctrlb then [ then you can use your normal navigation keys to scroll around (eg. Up Arrow or PgDn). Press q to quit scroll mode.

Alternatively you can press Ctrlb PgUp to go directly into copy mode and scroll one page up (which is what it sounds like you will want most of the time)

In vi mode (see below), you can also scroll the page up/down line by line using Shiftk and Shiftj (if you’re already in scroll mode). Unshifted, the cursor moves instead of the page.

Excerpts from the man page:

tmux may be controlled from an attached client by using a key combination of a prefix key, ‘C-b’ (Ctrl-b) by default, followed by a command key.

 The default command key bindings are:

[           Enter copy mode to copy text or view the history.

Function                     vi              emacs
--------                     --              -----
Half page down               C-d             M-Down
Half page up                 C-u             M-Up
Next page                    C-f             Page down
Previous page                C-b             Page up
Scroll down                  C-Down or C-e   C-Down
Scroll up                    C-Up or C-y     C-Up
Search again                 n               n
Search again in reverse      N               N
Search backward              ?               C-r
Search forward               /               C-s

Plus a bunch more. Note that you have to press C-b twice if you use that for page up since C-b is bound as the command key. See the man page for information on prefacing a copy mode command with a repeat count.

You can set the key binding mode using Ctrlb, then

:set-window-option mode-keys emacs

or vi.
