Use the transparency screen to type on top of PDF's, on top of tiles, flashcards, wordcards etc. To open the transparency screen click the

icon in the tool bar.

When the transparency screen is on, you can draw, use the stamps, type over the items on the screen behind it. Click the ^ arrow again to remove the transparency screen.

Tip: This works well when you need to type or draw in the margins outside of the PDF boundaries.
