Seems like the Linux part of Wikipedias Table of keyboard shortcuts article hasn't been updated in a while.
I went trough and removed/updated some deprecated stuff and added some stuff that wasn't there. For Gnome. And I learned some new stuff in the process.
But there's also some stuff there I'm not sure about and didn't touch even if I think maybe it should be changed. If you have some time, maybe you could have a look?
But I also wish #Gnome would not change keyboard shortcuts for no reason. Just keep using the things people have become used to, how are we supposed to learn the new one, and why? Shortcuts become muscle memory.
