I am looking for a way to raise/lower the sound volume without having to mouse the indicator applet. Ubuntu Mate 18.04 LTS, Cupertino layout
I have already set System Settings > Keyboard Shortcuts > Volume down to Ctrl+Alt+Down and Volume up to Ctrl+Alt+Up, but the keys don’t seem to affect the volume.
I have set Ctrl+Alt+Right and Ctrl+Alt+Left to change workspaces without problem, so I don’t think it is a non-standard key code problem.
Thanks!
