How to scroll up and down in Tmux

Do you know how to scroll up and down using your Tmux application? This has been a significant concern for those getting started with this application. When I started using this app, I had similar complications, and I did not know how to scroll up and down on Tmux.

This was because it runs multiple windows simultaneously hence becoming more complex to scroll up and down. However, after a lengthy hassle and tussle, I learned how to scroll in Tmux. Therefore, if you have been experiencing the same problems, I will illustrate how to scroll in Tmux.

Tmux is a top-notch open-source terminal/shell multiplexer for Unix-based operating systems, derived from the word “terminal multiplexer.” Tmux is a program that lets you use multiple terminals simultaneously from a single application window. It comes in handy when running multiple command-line scripts or programs at once.

Below are some methods you can apply to enable Tmux scrolling:

Enabling Tmux’s scroll mode

In Tmux, you can scroll up and down by using the following methods:

Press the Ctrl + B keys, then the subsequent “[]” key. To navigate the Tmux interface, use the standard keyboard navigation keys such as up/down arrows, page up/page down, etc.

When a user has finished scrolling, he can exit Tmux’s scroll mode by pressing the Q key. If none of the provided options works for you, try using the F7 key to jump into the scroll mode and q to exit the mode.

1. Use the VI mode

When an associated client controls Tmux, it is referred to as a VI mode in Tmux. Shift + K and Shift + J keys can be used in the VI mode to move line by line in the Tmux interface (if scroll mode is enabled); otherwise, the cursor will only move when the indicated keys are pressed. In the Tmux application, you may also use the C-B (twice) keys to scroll up a page and the C-F keys to scroll down a page.

Enable and employ the copy mode

Press the Ctrl + B keys, then the PgUp key.

Now the terminal will move one page higher in Tmux.

Alter the Tmux.config file

There are instances whereby the provided solutions will be insufficient; in such instances, altering the Tmux.config file may resolve the issue (as discussed below). You may open the Tmux.config file in the terminal by typing the script below:

vim ~/.tmux.config.

Activate mouse scrolling

Follow the steps provided herein to activate mouse scrolling:

Step 1: Add the following lines to the Tmux.config files, depending on your Tmux version:

For the Tmux version below, 2.1

set -g mode-mouse on

For the Tmux version 2.1 and up

set -g mouse on

Step 2: Check to ascertain that the mouse scrolling feature works flawlessly.

Remember that you may leave the scroll mode by pressing the Q key. Additionally, you might opt to copy the contents of the terminal by pressing Shift + Mouse Left Click.

Activate mouse scrolling with key binding

Step 1: To the Config file, append the following lines:

set -g mouse on
bind -n WheelUpPane if-shell -F -t = "#{mouse_any_flag}" "send-keys -M" "if -Ft= '#{pane_in_mode}' 'send-keys -M' 'copy-mode -e; send-keys -M'"

Step 2: Now, terminate the Tmux processes by performing the following:

tmux kill-server && tmux

Step 3: Run Tmux and verify that the scrolling works as expected.

If you need to copy an item while in Tmux’s mouse mode, use “Shift + left mouse click.”

If it doesn’t work, see if appending the following to Tmux.config fixes the issue:

set -g mouse on

bind -n WheelUpPane {

if -F '#{==:#{window_name},nvim}' {

send-keys -M

} {

copy-mode -e



Activate default Xterm scrolling

Modify the Tmux.config file as follows:

set -g terminal-overrides 'xterm*:smcup@:rmcup@'

Now verify that the Tmux scroll meets your expectations.

If it does not work, attempt the following: add to Tmux’s configuration file the line of code below (you may need to reboot your machine afterwards):

set -g terminal-overrides "xterm*:XT:smcup@:rmcup@:kUP5=\eOA:kDN5=\eOB:kLFT5=\eOD:kRIT5=\eOC"

However, if you switch the terminal type to Putty, the preceding code may not function; if you must use Putty, you may add the following to Tmux’s configuration file:

set -g terminal-overrides "putty*:XT:smcup@:rmcup@:kUP5=\eOA:kDN5=\eOB:kLFT5=\eOD:kRIT5=\eOC"

If this does not address the problem, you may consider adding the following to the configuration file:

set -ga terminal-overrides ',xterm*:smcup@:rmcup@'

Below is a list of the short key bindings you can use to scroll up and down in Tmux.

Half-page downC-uM-Down
Half-page upC-uM-Up
Search forward/C-s
Next pageC-fPage down
Search backwards?C-r
Previous pageC-bPage up
Scroll upC-Up or C-yC-Up
Scroll downC-Down or C-e C-Down
Search againnn
Search again in reverse modeNN

Note: Scrolling with keys is primarily enabled on Tmux. Therefore, you should always use this method before trying other alternatives provided in this article guide.
