Narrative:

During the takeoff roll at about 90 KTS; the stabilizer trim alert on the ead came on and I saw the stab trim rolling toward 0 degrees anu. I aborted the takeoff. After we stopped the first officer told me he had accidentally moved the trim switch on the yoke. I called dispatch and maintenance and told them what happened and after about 10 minutes; the #1 brake reached 200 degrees. Only the left brakes were heating up. The right brakes were about 90 degrees. Both maintenance and I agreed we should return to the gate to have the brakes and wheels checked. By the time we were at the gate the hottest brake was 140 F. The brakes checked ok and we departed uneventfully. I don't think the first officer will ever do this again. He was really bothered about what he had done. I told him to relax; we all make mistakes; as long as we learn from them.
