Audio source menu keyboard shortcuts and navigation

[atenonai]

It would be nice with some keyboard shortcuts and navigation for the play audio menu.

Currently you need to right-click on the play icon with the mouse to bring up the list of audio sources, and then click on one on of them to play the audio. The menu then goes away automatically, and you need to repeat this process for every source you wish to hear.

This process quickly becomes frustrating when you want to listen through and compare multiple pronunciation before selecting which source to use.

If instead the sources menu could be brought up with a keyboard shortcut, and the user could navigate up and down in the list (without it closing) to autoplay each source before selecting one, I think it would make for an improved experience.
