Set scroll speed in Tmux

Tmux is one of the most useful tool when it comes to using using a linux terminal.

Tmux is a terminal multiplexer, it allows a user to access multiple terminals (or windows), each running a separate program, while providing a single screen to work on. Tmux is useful for running more than one command-line program at the same time, increasing productivity and the way you work.

Open ~/.tmux.conf file using vim or your preferred text editor.

vim ~/.tmux.conf

Then, append the following config in the ~/.tmux.conf file

set -g mouse on

set-option -g status-keys vi
set-window-option -g mode-keys vi

bind-key -T copy-mode-vi WheelUpPane send-keys -X halfpage-up
bind-key -T copy-mode-vi WheelDownPane send-keys -X halfpage-down

Now save the file. In case of vim, its ESC + :wq + ENTER.

Let's say you have made changes to tmux.conf file by adding or changing default config, you have to reload the config so that the changes reflects in your terminal. The command to reload config is called source-file.

You have to reload tmux.conf so that it reflects-

tmux source-file ~/.tmux.conf

If you are inside a tmux session, you can run the command inside the tmux session to source the config file-

Ctrl-B
:
source-file ~/.tmux.conf
