Question: Quick-hide desktop icons?
I like a clean desktop and for several years have used an app called TinkerTool to hide/unhide all the icons. It is a simple app which doesn't mess with the OS but just drops out to toggle a command line option. Quite by accident, I recently discovered that, when no apps are open, the standard key combo of Cmd+Q also hid all the icons, as if it was quitting Finder. Clicking Finder in the Dock restored the icons. Since this was quicker than launching a third-party app and allowed me to remove TinkerTool from my Dock, I thought this was a nifty little feature I would use a lot.
But it ain't. Mostly it doesn't work. Sometimes it does, but I can't predict when. Does anyone know whether this is an actual High Sierra feature? A bug? Does anyone have knowledge about the conditions under which it works? Is it dangerous?
