From: Tony Lindgren <tony@xxxxxxxxxxx>
Let's configure the keypad in a way where it's usable out of the
box for Linux console use. To do this, let's follow the standard
PC keyboard layout for ctrl, shift and alt keys:
Ctrl = what is labeled as shift
Alt = what is labeled as SYM
Shift = what is lableled as caps lock
Meta = what is labled as OK
Who knows where they got the caps lock idea.. Probably from
some focus group popularity vote or something.
Note that some other keys don't match the labels either as they
don't follow the PC keyboard style. For example we have "shift + ,"
produce "<", and "shift + ." produce ">" instead of ";" and ":".
Pretty much Esc is the only key missing. I've used "Meta + 1"
produce Esc, and that seems to work OK. But that can be mapped
using the standard userspace tools.
