Very simple. Just follow these steps.
- Open a book by tapping on it in your library
- Go to a page that has text on it
- Tap once on the middle of the page
- Now you see a ReadMe!-mark highlighting a word with red. If you tap once on this, the Spritz view will appear and start Spritzing from that word.
- (Optional) If you want to start from another word, just drag the ReadMe!-mark!
( This is what the ReadMe!-mark looks like )
