The plasmoid to select the source/ sink/ mute and volume for sound is not keyboard navigateable
Reproduce:
Click on volume icon in panel
arrow up/ down or press tab
result:
- the list entries (devices) are never focused
- the volume sliders can not moved (increase decrease volume)
- only the embedded "hamburger" menu is focused and can toggled with space (thats good)
- the page could not changed (from Devices to applications)
What should happen:
- the list entries (devices) should be focused, pressing arrow left/right should select the volume,
- pressing tab should focus the hamburger menu for the selected list entry
- pressing up /down should move in the list up or down
- a way to change the page, (maybe ctrl + page up/ page down or make it focusable in tab chain to activate it with space bar)
