Narrative:

At FL280 on the TIGGR1 arrival; the first officer was adjusting the thrust levers and inadvertently hit the toga buttons and looked at me. I instructed him to fly the aircraft. He took the flight controls and pitched into the flight bars. Realizing the pitch of the toga buttons was indicating a climb; I told him to descend. He did not react immediately to my instruction. I pushed forward on the yoke. We climbed 200-300 ft above FL280. We descended back to altitude. We discussed the use of automation. Also verifying the flight director compared to what the aircraft should be doing.
