I have a notebook with no dedicated (working) keys for volume, so I've set under the Shortcuts Settings to use Win+Up/Down to change volume. That's working fine and I get that nice popup showing the volume level when I press this shortcut.
But I've bought a keyboard with dedicated keys, and I want to be able to use BOTH. Thus, I would need to copy the initial shortcut... But I have no idea of what command the original shortcut fires. I've tried
amixer command: it works, but there's no visual cue of the volume level.
