Locking the Keyboard
 

Does anybody know of any way to lock/unlock the Kindle 3's keyboard?

Basically, so that while reading I don't get that "search" box popping up at the bottom of the screen if I accidentally hit a key on the keyboard.

Also, while I'm thinking of the controls, anything which allowed me to remap the page turning buttons would be good too (personally, I'd just prefer it if the buttons on the left side were reversed, so that "next page" was upper-left and lower-right while "previous page" was lower-left and upper-right, as that would feel more natural to me).

Reversing the left buttons would be nice, but as far as I know there is nothing like that. As for the keyboard lock there is nothing like that either. Your zero for two, sorry.
