I've done steeks and there's no special trick to it. The steeks I've done have been on very thin yarn, so there were no loops to catch on the parts of the sewing machine. I have read, though, that if you have trouble with catching, you can put a piece of tissue--the gift wrap kind--under the knitting to prevent that. Just tear it off afterwards.
