How to enable Mouse and Touchscreen Support on Mosh?

Why doesn’t mosh support scroll? What is the workaround to add a scrollback buffer in Mosh? How do you pair tmux or screen with Mosh for an enhanced experience? Can you mouse scroll inside VIM or Emacs?

The main reason why Mosh is so fast is because it only needs to synchronize changes between your screen and the remote, like in video streaming. While Mosh itself doesn’t have a scrollback buffer, you can pair it with multiplexers like Tmux or Screen, or text editors like Vim or Emacs, Enabling mouse support comes in handy when using an iPad without a keyboard, or if you simply prefer to swipe on the touchscreen, as you can freely change panes in tmux or scroll through your apps with your fingers.

Blink provides mouse and touch support out of the box, so let’s delve into the configurations for specific command line applications:

TMUX:
In your tmux configuration (usually ~/.tmux.conf), add the following line:

set -g mouse on

SCREEN:
In your screen configuration (usually ~/.screenrc), add the following line:

termcapinfo xterm* ti@:te@

VIM:
Edit your vim configuration (usually ~/.vimrc), add the following lines:

set mouse=a

Emacs:
In your emacs configuration (usually ~/.emacs), add the following lines:

(xterm-mouse-mode 1)
(global-set-key [mouse-4] 'scroll-down-line) 
(global-set-key [mouse-5] 'scroll-up-line)
