[kwlug-disc] Presentation Pointer

[Khalid Baheyeldin]

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

https://www.ebay.ca/itm/2-4GHz-Wireless-Presenter-USB-Remote-Control-Presentation-Mouse-Laser-Pointer-CA/112366784517

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?
