1. Double tap or press and hold any word.
2. Tap copy.
3. Tap screen at the top to bring up the reference window. (It doesn't matter if it is a novel or Bible.)
4. Tap the reference window to get focus.
5. Tap the x in the window to erase the current script.
6. Tap the window twice.
7. Tap paste.
8. Tap your pasted word twice.
9. Tap define. Your definition will appear in a drop down window. After a few times this procedure goes quickly. It works for Vyrso too. It doesn't change the page you are on.
