Manager's keylock
Provided by the ASK Keyboard Dictionary
Aka/also known as: operator keylock
A manager's keylock is a point-of-sale security feature used to access sensitive functionality on POS computers and terminals. This keylock is typically found on POS monitors or keyboards. For IBM and TGCS POS keyboards with such a key-lock, it typically has two positions; "system" (normal access) and "manager" or "operator" (privileged access). When the key is turned, the host keyboard can send a scancode to the host POS computer or terminal to indicate this change. The position of the key can also modify the scancodes the System keys ("S1" and "S2") return.
