PuluseAudio Volume Control gui does not have keyboard shortcuts
I want to set PulseAudio up to control the volume on my system no matter what is currently being used to play audio or video. If I am playing music with VLC, Audacity, DragonPlayer, JuK, mpv media player, SMPlayer, etc. or watching a video in Firefox; I want PA controlling the volume; and I want the volume down and volume up keys on my keyboard to be what I use to modify the volume. However, there is no place in the gui PuluseAudio Volume Control to set that up.
Why does this not have a keyboard configuration section?
I tried setting up the keyboard in XFCE's keyboard settings, but the commands do not work.
So, please add keyboard configuration for volume down, volume up, and mute keys on keyboards with an onscreen indicator when the volume is being changed or muted.
