Many of the wireless keyboards and Natural Keyboards from Microsoft have the
F-Lock key.
Here is a description of what the F-Lock does from a 3rd
party website (

F
Lock Key
The F Lock key on the Microsoft Keyboards is a relatively new
concept facility for Microsoft Keyboards. Introduced with the Office Keyboard
and used in later keyboards, it essentially allows keys to do more than one
operation. The F Lock key, depending on its state, will allow either a function
key's "normal" operation or a new "enhanced" operation. The initial state of the
F Lock key is "off", and in this state, the function keys use their "enhanced"
operation.
The F Lock key is a hardware switch in the keyboard. Its state
cannot be controlled programatically. Its default condition is "off". As a
result, whenever the keyboard is reset, or loses power, the F Lock key will
always be in an "off" state.
For some, this is not a desirable default;
some people want "normal" function key operation.
Does it ask for a password??
