In page Recorder (musical instrument):

"

The open end of the bore facing away from the player (the "bell") may be covered to produce extra notes or effects. Because both hands are typically engaged in holding the recorder or covering the finger holes, the covering of the bell is normally achieved by bringing the end of the recorder in contact with the leg or knee, typically achieved through a combination of bending of the torso and/or raising of the knee. Alternatively, in rare cases instruments may be equipped with a key designed to cover the bell ("bell key"), operated by one of the fingers, typically the pinky finger of the upper hand, which is not normally used to cover a hole. Fingerings with a covered bell extend the recorder's chromatic playable range above and below the nominal fingered range.[citation needed]
