Assuming the presence of xorg, perhaps xmodmap is the next place to
look?

I got a 2.4GHz Presentation Laser Pointer from eBay. It has
a small USB dongle, and 4
keys.

The same pointer is sold under known brand names, such as Targus,
...etc.

When I plug it in, it is recognized as a
keyboard:

When I start LibreOffice
and press the buttons, nothing happens.

When I open a Terminal from
XFCE, nothing happens.

But when I press Ctrl-Alt-F2 and login to a
native terminal, the escape codes do show up in that terminal.

Here is
a hex dump of the four buttons, separated by some dashes. All four
buttons do send stuff. Three send escape codes, and one sends just a
plain lower case b.

00000000 1b 5b 35 7e 2d 2d 2d 2d 2d 62 2d 2d 2d 2d
2d 1b |.[5~-----b-----.|
00000010 5b 36 7e 2d 2d 2d 2d 2d 1b 5b 33 31 7e
2d 2d 2d |[6~-----.[31~---|
00000020 2d 2d 0a |--.|

So, my question is,
how to make such a 'keyboard' work from LibreOffice under XFCE?
