Just like in Drawings, you can add wordart in slides
The cool thing is that in slides you can also animate the word art-this means you can make it move!
1) Click the INSERT menu
2) Click Wordart
3) In the box, type the word or words you want to use for your wordart
4) You can change the FONT, the FILL or inside colour, the OUTLINE colour and the WEIGHT or thickness of the outline. You can also drag the anchor points from the corner to make it bigger or smaller.
5) When you select your word art, you will see an option in the toolbar to ANIMATE. You can choose how the wordart moves and whether this happens ON CLICK or AUTOMATICALLY and how FAST it moves.
