vCenter Break Out of Console

I checked a server at work and logged onto vSphere/vCenter. I found the server and clicked the console tab.

I clicked on the console screen, it was a Linux OS. I tried to move my mouse but it wouldn't come back to me in Windows.

Only then did I realize I had to break out of the console window somehow.

I pressed Ctrl-Alt-Del, thinking that the Windows 7 OS would lock, I could unlock it and then have control back.

But instead it sent the signal to the OS and immediately rebooted the server!

I learned late that pressing Ctrl and Alt simultaneously will break you out of the console in vCenter.
