I have connected two notebooks via USB-C. This works perfectly so far. I can display both computers at the same time, as well as switch computers using the on-screen buttons and the KVM (i.e. keyboard and mouse) also switch. What doesn't work, however, is switching with the HotKey. The instructions say that you can switch from one computer to another by pressing Ctrl 3 times. After pressing three times, nothing happens at all. After pressing twice, a bright circle about 5cm in size appears around the mouse and the rest of the screen is darkened (like a kind of spotlight). I don't understand what the point of this is. Does switching via HotKey work for anyone? And if so, what am I doing wrong?
