May 2013: Subscribe for Free Daily Emails that list 95 free kindle books every day. Hand-curated.
(courtesy Igor S’s excellent Blog Posts on Reverse Engineering the Kindle - this is taken verbatim). Again this is best read on Igor’s blog. And his work is the basis of nearly all the good tips and tricks related to the kindle you might find.
I’m not sure why Amazon didn’t make it public (maybe because paging is kinda slow), but there is a basic picture viewer in Kindle.
To activate it:
1) make a folder called “pictures” in the root of Kindle drive or SD card. Kindle also checks for “dcim” made by cameras.
2) put your pictures for a single “book” into a folder inside that. The subfolder name will be used as the “book” name. Supported formats are jpg, png, gif.
3) in Home screen press Alt-Z. A new “book” should appear. Open it to view your pictures.
4) In the local menu you can toggle dithering, resize to fit and full screen mode.
Various undocumented/underdocumented keyboard shortcuts. I italicized most interesting ones.
Alt-Shift-R reboot Kindle
Alt-Shift-. restart GUI
Alt-Shift-G make screenshot
due to an implementation bug, screenshots can only be stored on SD card, not the main storage. A gif file is saved in the card root.
Shift-Sym start demo
Enabled only if allow_demo=true is passed on the Java commandline. Needs a special demo script present on the SD card.
Alt-Z rescan picture directories
Alt-T show time
Alt-B toggle bookmark
Alt-T spell out time
Alt-0 enable/disable slideshow
Alt-1 start slideshow (if enabled)
Alt-2 stop slidehow
Alt-PageForward/PageBackward go to next/prev annotation or one “chunk” (1/20th of a book) forward or backward
411 show diagnostics data
511 run loopback call test
611 diagnostic data service call

(the following don’t work in search field for some reason)
It seems there is a location capability (GPS?) in the CDMA module. I cannot check it as I’m not in USA but the following shortcuts are programmed inside the browser.
Alt-1 show current location in google maps
Alt-2 find gas station nearby
Alt-3 find restaurants nearby
Alt-5 find custom keyword nearby
Alt-D dump debug info to the log and toggle highlight default item
Alt-Z toggle zone drawing and show log
These command work in the search field. You can enter only beginning of the command if that’s enough for it to be unique.
Public commands (always available)
Semiprivate (available but not mentioned in @help)
;dumpMessages dump current debug log into the “documents” directory
;debugOn set log level=2 and enable private commands
;debugOff set log level=1 and disable private commands
