Not the first time this has happened. Pilots need to slow down and LOOK where they're reaching.

Narrative:
ANA Flight 140 was en route at FL410 when the first officer inadvertently used the rudder trim knob instead of the flightdeck door lock knob. The captain was returning to the flight deck when the first officer needed to unlock the door.
Consequently the airplane banked left to a maximum of 131.7 degrees and entered a steep descending turn. Control was regained at FL347.
During the event, the speed limit (Mach 0.82) was exceeded when the airplane flew at Mach 0.828. Also the acceleration limit (+2.5 G) was exceeded when the plane hit +2.68 G.
