Is your feature request related to a problem? Please describe.

No, it is not.

Describe the solution you'd like

I would like be able to bind the volume to scroll, hence allowing the keymaps to be able to listen / match mouse scroll inputs.

[[keymaps]]
command = "VolumeUp"
key_sequence = "ScrollDown"

[[keymaps]]
command = "VolumeDown"
key_sequence = "ScrollUp"

Describe alternatives you've considered

Using my mouses software I theoretically could add a unused keys to the scroll directions, then use keymaps with those keys.

Additional context

This can be done on the default Spotify client by hovering the volume bar and scrolling.
