Current versions of gnome’s “Keyboard shortcuts” control panel applet don’t have an entry for “System->Show the activities overview“, so you can’t edit it. Instead, it’s hard coded to the winkey, and Alt-F1. No. Bad gnome. Don’t do that. I want to use that, (in my case, in IntelliJ)
What to do?
gsettings to the rescue.
$ gsettings get org.gnome.desktop.wm.keybindings panel-main-menu ['<Super>s', '<Alt>F1'] $ gsettings set org.gnome.desktop.wm.keybindings panel-main-menu "['<Super>s']"
