KEYBD command states "n can be either 0 to turn off the toggle or 1 to turn on the toggle". Below it explains "/K(eyboard lock)". This implies that /K0 turns off keyboard lock, and /K1 turns on keyboard lock. This conflicts with the details of option /Kn: "Disable (0) or enable (1) the keyboard. I'd change the wording of the summary to "/K(eyboard unlock)". BTW, below the "Options:" heading /Kn shows the parameter, the other options do not.
