Hardware

The ALPS Electric KGDMFA001 provides both Touch Pad/Tablet and keyboard.

80+ keys, 1.0mm stroke; sealed rubber-membrane key-switch assembly. (from Hardware specification#Integrated_peripherals).

Specification: File:KGDMFA001-non-confidential.pdf (towards bottom).

Non-keyboard keyscodes

As of 15:22, 19 June 2007 (EDT) the handheld-mode keypads bind to

Right-hand side: up/down/left/right
Left-hand side: KP_PAGE_UP/KP_PAGE_DOWN/KP_END/KP_HOME

Layouts

We have a single keyboard model (the hardware; geometry and keycodes), but many layouts (the printing on the keys). Both are (or will be) listed in /usr/share/X11/xkb/rules/base.xml .

I believe we do not yet have an xkb geometry file. MitchellNCharity 00:49, 3 October 2007 (EDT)
