While these shortcuts could be useful enough, the Magnification rate is increased/decreased by 1 which is just too much for me. There won’t be any visible effect unless you update the Magnification rate, there are shortcuts to do so: This is relatively simple, just go to Settings -> Accessibility, tweak the options until you find what works for you, then, enable the Zoom option. Optionally switch the UI server from Wayland to Xorg so that the shortcuts work at Gnome desktop/terminal.Let’s integrate xbindkeys to define mouse/trackpad shortcuts to invoke our zoom in/out scripts, be aware that it won’t work at Gnome desktop/terminal.Let’s create 2 bash scripts to increase/decrease the zoom level.Ubuntu 22.04 will enable shortcuts to update the zoom level by 1 while I prefer to set 0.2 as the rate. Let’s enable the Zoom feature on the accessibility settings ( Settings -> Accessibility -> Zoom), tweak them to the way you like them and keep the Magnification rate at 1.00.

Holding alt + trackpad scroll-up triggers zoom-out.Holding alt + trackpad scroll-down triggers zoom-in.Let’s start with a demo showcasing the final integration: Its been years since the last time I used MacOS, Pinch to zoom is the only feature I have missed from it, while I have used workarounds, I finally put enough time to get this feature working on Ubuntu 22.04, this post explains how I did it.
