I just updated to Fresh 3.1 and i have 2 questions

1. On the keyboad near lower left there is a button "En" that changes to "Es" when pressed. What is it?

2. On several videos that i saw regarding Froyo they would show "pinch peek" on 3D gallery. i cant seem to reproduce the action (zooming on the folders gives you a "peek" of the photos within folder). Does anybody have that feature?

thanks.
