Right now on the PlayBook there is a pretty easy gesture from the corner to show and hide the keyboard. On BlackBerry 10 it looks like RIM will be changing that gesture up a bit for the keyboard. According to the design documentation we just mentioned users can show the virtual keyboard by dragging two fingers from the bottom of the screen. The same process in reverse swiping down will hide the keyboard. Obviously the keyboard will still show and hide when you focus or lose focus on a text field.
Personally I am very curious to see what RIM does with gestures in BlackBerry 10. I am really hoping they take it to the next level with the phones. They have already shown some of this off with the peeking gesture but there is definitely room for more. Personally I really hope they keep the swipe from bezel to bezel to unlock gesture.
Thanks Peter for pointing this one out!
