Different products have different switching modes, such as "FL/ Fei Lan" KVM switch, and a VS- 1008KVM switch with various hot keys, which you can choose from. The selection hotkeys provided by this device are: scroll lock, number lock, left Ctrl, right Ctrl, left Alt, right Alt, left Win and right Win. Because what I just said is the most comprehensive, the hotkeys of other switches are basically in it. Next time you encounter such a problem, it is really impossible to try all the above methods, and maybe the problem will be solved.
