This means a two char sequence: e0, 0x56 is stuffed into the
kernel device kbin. Ultimately thsi will map to the value in
kbtabesc1[0x56]. Now kbtabesc1 is table 2 in a kbmap so we are
looking for an entry that starts with
2 86 ... # 86 == 0x56
In /sys/lib/kbmap/de I see
2 86 0
This explains why you don't see anything. What you want to do
is to copy this file to, say, de2 and replace the above with
2 86 '<
And then put the following in $home/lib/profile
cat /sys/lib/kbmap/de2 > /dev/kbmap
Probably under 'case terminal'.
Repeat this analysis for other keys that don't work right. I
did a quick reading so may have missed something but hopefully
you can follow the code yourself now. You will have to look at
the following files
/sys/src/cmd/usb/kb/kb.c
/sys/src/9/port/devkb*.c
/sys/src/9/omap/kbd.c (what 9/bcm/kbd.c points to)

This won't work. The first item selects a scanmap (a 128
element array). The second item is an *index* into this
array. The third item is the Rune that goes in that slot.
See kbmap.c to find the mapping between table number and
a kbtab* array.
