I've been looking for some time now for a way to turn off my computer with a combination of keys, without the need to confirm, or with a simple key confirmation (ex. pressing Enter).
I have a Tuxedo computer with recommended OS, I think it is a mixture of GNOME, Cinnamon and Budgie, I know those are not exactly the same thing but part of the problem is I don't know who's the owner of something specific.
This was for context, and I now it may seem that it deviates from my problem, but now I really want to learn when I press the super key to start a menu and I start typing, where do the search menu results come from?

The first, "Applications", is from applications installed. The second "Application Actions" is from the desktop files that exist in /usr/share/applications or ~/.local/share/applications. Where can I find info about the third menu "Actions"?
