Thanks for the great hack!
This is a fantastic hack!
I've been trying to make a custom keyboard for my Kindle 3 for a while now, and ran into problems turning individual pages. Turns out the main keypad's 5-way can only jump between chapters, not individual pages.
The solution? Launchpad. Tonight I successfully mapped the 5-way's Left and Right buttons to turn individual pages, and the hardest part of my project is now done!
Thanks to h1uke for the hack itself and everyone else in this thread/forum for the help and clarification. You guys rock.
