[Trisquel-users] Multimedia keys on Trisquel with i3

[behmen]

I'm using i3wm and my external keyboard's multimedia  
(previous,play/pause,next) keys aren't working. I tried to add

# Media player controls
bindsym XF86AudioPlay exec playerctl play
bindsym XF86AudioPause exec playerctl pause
bindsym XF86AudioNext exec playerctl next
bindsym XF86AudioPrev exec playerctl previous
that I found on i3 forums, but Trisquel doesn't have playerctl. I try my best  
not to download un-audited things straight from github

Multimedia keys however are working with MATE, so my question would be which  
program can I substitute for playerctl?

Thanks!
