   That's the Enter key.  Nothing to worry about.

   This is "KEY_MICMUTE".  That can easily be added to acpid by adding 
the following lines to input_layer.c:

    {{{0,0}, EV_KEY, KEY_MICMUTE, 1},
       "button/micmute MICMUTE 00000080 00000000"},

   Add them to the "/*** AUDIO ***/" section.  Rebuild and try it. 
acpid should receive mic mute events.  This doesn't mean it will do 
anything with them.  You'll need to add a config file and a script to 
make something useful happen.  See the man page.

   If this works and you find this helpful, let me know and I'll include 
this change in the next release.

   If you just wanted the mic mute button to work in your window manager 
(e.g. Gnome or KDE), then it's best to get them to support these 
keys/buttons.  acpid is geared more towards those who are not running a 
window manager (servers).  You can still use it for this, but it's not 
really the best solution.

   Your script for acpid will need to turn the light on and off.  Most 
likely, your window manager is doing this already for the mute button, 
but it is not aware of the mic mute button and the LED.
