Narrative:
At FL350 encountered unforecast moderate to severe clear air turbulence and mountain wave activity. Speed trend arrow started to rapidly increase. I closed the throttles to no effect; reached down to extend the speed brakes and accidentally moved the flap handle toward/into the flaps 1 position. Realizing that I moved the wrong handle; I placed it back to the up position. Sent message to maintenance that read; 'flap handle moved to flaps 1 at 250 knots indicated.'
