This post briefly summarises a variety of keyboard commands and shortcuts I’ve picked up from various places and found useful when experimenting with my Kindle 3
Commands / Debug mode
There are a number of commands available in ‘debug’ mode, which are entered via the Home page’s “Search” window. Reach the search window simply by pressing <delete> while at the Home page.
Activate debug mode, after which additional commands may be entered via the Search window

~help or ~h
Copy the internal linux firmware’s console output to a date-stamped file at the top of the K3’s USB mass storage file system. This file can read and searched as a regular document on the K3, or retrieved by any PC when the K3 is plugged into the PC’s USB port in mass storage mode. (If you’ve enabled SSH access to your K3, you can also retrieve the file from the /mnt/base-us/ file system.)
;dumpMessages
usbNetwork is a program that requires a jailbroken K3 with the usbnetwork hack applied. Each time it is executed, the K3’s USB port toggles between networking and mass storage modes.
~usbNetwork
Commands relating to battery condition
If you’ve jailbroken your K3 and enabled SSH logins, the following command line commands provide insights into the battery state.
