Without knowing what buttons you have I'll just throw out some
suggestions. Wifi, sleep/hibernate, battery status, brightness up/down,
and various zoom buttons are some of the ones that I see on the NB505.

On Debian/Ubuntu it's in the input-utils package, I don't know about
other distros. Source is at

Basic instructions are to use lsinput to identify the device you want to
test, then pass the event device number as the argument to input-utils,
which will dump the raw events that come out for only that device. Your
hotkeys should come out of either the device named "Toshiba input
device" or "AT Translated Set 2 Keyboard", or some on both.

Have you tried it with the -s argument to see if a scancode is produced?
Both the Toshiba and AT keyboard input devices should leave a message in
dmesg though if they see an unknown scancode though.
