You are right. I stand corrected. I had been trying to do it with a newspaper Calibre uploaded and couldn't get it to work for some reason (I have a sneaking suspicion it may be because the newspaper was formatted for iPad since I'd wanted to try it on my iPhone, though I never bothered since transferring it was too much trouble). However, with a regular book in ePub format, it does work, though I'm finding the buttons to be more responsive anyway so will likely stick with those. Thanks. And on to the other question. . .
