This works fine, thanks. IMO, it is better than command 0x8e.
I also found that register 0x07 controls the cursor keys emulation:
* 87 03 07 07 00: disable
* 87 03 07 03 00: enable (03 or 03
* 87 03 07 00 00: set "joystick mode" (?)
But I cannot find a similar register to disable the enter/esc keys, for
that I still need commands 0x85 and 0x81.
Can you tell me if there is a register to configure the enter/esc
emulation? That would be nice, because I could enable disable the lizard
mode with a single report: (87 09 07 07 00 08 07 00 xx 07 00).
Thanks.
