Going to keep this one short and sweet.
The hot key for a IOGEAR GCS634U KVM is scroll lock + scroll lock + port number + Enter. Or to put it another way, double scroll lock, then the number (1-4) of the KVM port you want to switch to, then press Enter.
I was using a for the first time in a while and could not remember the correct hot key combination to switch the video input. I was in a bit of a hurry and had to do a little digging before I found the answer. So after that I wanted to put this up in case I can save someone some time when searching for the key combination. Also, I'm pretty sure this hot key also works on the GCS632U as well as many other KVMs.
