The Toshiba Z830 has 3 hotkeys which use the ACPI PNP0C32 quickstart spec:

These devices have an ACPI method called GHID() which suggests
it returns a value from the "HID Usage Tables" document, but these
methods simple returns a follow number for the button (1, 2 and 3).
The first 2 buttons are for what the manual calls "TOSHIBA eco button"
and "TOSHIBA Presentation button", since there is no good match for
these simply map them to KEY_PROG1 and KEY_PROG2.
The third button is intended to toggle the touchpad on/off, map
this to F21 which GNOME/KDE will interpret as touchpad toggle.
