Today I learned how to switch screens via keyboard on an Ugreen HDMI KVM switch. If your keyboard is connected to the switch’s keyboard port, just press Ctrl, Ctrl, Enter (in sequence).

This seems to be an undocumented feature, as I couldn’t find any mention to it in the official documentation. I discovered this feature after accidentally pressing that sequence more often than desired.

If I plug my keyboard on the general USB port instead of the keyboard-specific one, the switching doesn’t work.
