I just learned this at the training on November 28! Double click on the start button and slide the menu bar from left to right. This will allow you to make adjustments to several things. I was happy to find that I could lock the position of the display so that no matter how it was turned the image would stay put. This was a great discovery for me because I often have students check the bus routes on line. I am not sure why, but the file of the routes are oriented sideways. Before, I would turn the iPad and it would always display it sideways. If I held the iPad vertically, it would appear horizontal and vice versa. I was very happy to find this!
