From the brilliant Igor Skochinsky at
http://igorsk.blogspot.com/2007/12/hacking-kindle-part-3-root-shell-and.html Keyboard shortcuts
Various undocumented/underdocumented keyboard shortcuts. I italicized most interesting ones.
Global keys
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.
