I find this button pretty useless and I like That Was easy button. So the use is pretty clear. Download the sample:
wget http://mhwalkers.freevar.com/sounds/that_was_easy.wav -O \
~/.cache/what_was_easy.wav
Load the sample:
pactl upload-sample ~/.cache/that_was_easy.wav that_was_easy
This obviously works only for PulseAudio users. Always test before use!
pactl play-sample that_was_easy
Now bind this to the ThinkVantage button. In my case (i3 tiling windows manager) it’s:
bindsym XF86Launch1 exec /usr/bin/pactl play-sample that_was_easy
You can use xbindkeys program if your windows manager cannot handle this:
$ cat ~/.xbindkeys
"/usr/bin/pactl play-sample that_was_easy"
XF86Launch1
Have fun! :-)
