# Function-Key Unicode Values

Constants for reserved keyboard function keys that correspond to unicode characters.

## Discussion

These constants correspond to unicode characters in the range (0xF700–0xF8FF) and are values you can use with the [`characters`](/documentation/AppKit/NSEvent/characters) and [`charactersIgnoringModifiers`](/documentation/AppKit/NSEvent/charactersIgnoringModifiers) properties of the event. You can also use them in some parameters in the [`keyEvent(with:location:modifierFlags:timestamp:windowNumber:context:characters:charactersIgnoringModifiers:isARepeat:keyCode:)`](/documentation/AppKit/NSEvent/keyEvent(with:location:modifierFlags:timestamp:windowNumber:context:characters:charactersIgnoringModifiers:isARepeat:keyCode:)) method of the event.

Note that the system handles some function keys at a lower level and your app never sees them. Examples include the Volume Up key, Volume Down key, Volume Mute key, Eject key, and Function key found on many Macs.
