+ @url{https://github.com/baskerville/sxhkd, sxhkd} daemon to capture
+ X11 key events and execute commands:
+
+@example
+$ mkfifo /tmp/vors-mute-toggle.fifo
+$ cat >sxhkd.cfg <<EOF
+XF86AudioMute
+ herbe $(cat /tmp/vors-mute-toggle.fifo)
+EOF
+$ [run sxhkd]
+$ vors-client [...] -mute-toggle /tmp/vors-mute-toggle.fifo
+@end example
+
+ That will toggle mute on "audio mute" event and print its current
+ state as a @url{https://github.com/dudik/herbe, herbe} notification.
