Enter, for one (3)

Ross

I believe the answer is:

key

'enter for one' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for key that I've seen before include "Essential; solution" , "One that locks" , "Eg, Ctrl, Alt or Esc" , "Typewriter button, isle" , "Scale system for music" .)

I've seen this clue in The New York Times.
