The default implementation returns YES, accepting first responder status. Subclasses can override this method to update state or perform some action such as highlighting the selection, or to return NO, refusing first responder status.

Use the NSWindow makeFirstResponder: method, not this method, to make an object the first responder. Never invoke this method directly.
