I'd like to remap Command+s to save files in Atom, but I can't figure out where to disable the workspace overview feature that's already mapped to it. Any ideas?
You can change the key
gsettings in a terminal window. It defaults to
['<Super>Down', '<Super>s'] so if you only want to disable Super+s you can set it to ['down'] for instance.
$ gsettings set org.gnome.desktop.wm.keybindings show-desktop "['<Super>down']"
