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.

    Have you tried using the magnifier?

    What terminal are you using? What do you mean "zoom"? Increasing the text size or actually zooming?

  • I haven't tried using the magnifier, but I want to be able to type a command into the terminal and have it zoom (actual zooming). I'm using whatever terminal comes with Ubuntu 14.04.

  • @AmagicalFishy the magnifier can be launched using a shortcut, so you can write an xdotool command similar to these to launch it.

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).
