Wow! That is much better support for PDf on a 6" screen than what I expected. I hope they port the contrast adjustment and margin narrowing functions to my Kindle DX Graphite.

Very nice videos!

BTW, you can press Shift+Alt+G keys similtaneously to take a snapshot of the screen. (Shift is the key next to the Alt key with an up arrow on it.) The snapshot of the screen will be saved as a GIF in the Documents folder on the K3 with a name similar to screen_shot-8443.gif. At least this works on the KDXG.
