Terminal Command to Zoom

Question

I've been looking for this for a while, and I can't find it anywhere.

I need to be able to zoom (equivalent of ctrl + shift + '+') via the terminal. I've tried xdotool, but do not know how to get it to register '+' (or the = key).

This is very important and has been a life dream of mine. Now that I'm somewhat capable with Ubuntu, I feel that I can finally achieve this goal: I need to make an alias such that when I type in "enhance", everything zooms.

Answer 1

The xdotool (command-line X11 automation tool) commands to use are:

• Zoom in (AKA Ctrl++)

   xdotool key Ctrl+plus
  

• Zoom out (AKA Ctrl+-)

   xdotool key Ctrl+minus
  

• Normal size (AKA Ctrl+0)

   xdotool key Ctrl+0
  

This won't work on Wayland (echo $XDG_SESSION_TYPE).
