1. It's not a button. It's just a label to indicate that you're in preview mode. You get in and out of preview mode by hitting ctrl+p or clicking the empty right margin.
2. It inserts a tab when you hit shift+space. I initially put this in because I thought it would be an easy way to get tabs on the iphone, but apparently the ios shift key is not really a sift key so it doesnt work on the iphone anyway. Have to remove this.
3. Ctrl+s or click the empty left margin to save. The repeat prompt will be changed to prompt on first save only soon.
