I was told KDE in Debian 9.4 was old and maby therefor zooming and inverting werent able to use, but now i have booted the live disk of kde neon and im not able to zoom in or out and either invert colors.. I was told the keyboard shortcuts was:

Invert colors
meta + ctrl + i/u

Zoom:
meta + =
meta + -

But either works? Is it really true that accessability is so hard to use in kde neon?

I'm aware that this is very old, but for anyone wondering, you need to enable these in Desktop Effects. Just search for desktop effects in the application launcher, click it, then toggle the checkboxes for zoom and invert colours.

You can modify the shortcuts for these here also by clicking the config button over to the right. If you can't see the configure button, make sure you're hovering the mouse over the effect you're interested in so it's highlighted.

Maybe there's a way to toggle these on without needing to go into desktop effects but this is how I do it..
