audio related shortcuts behaviour
The A hotkey and corresponding UI button should no longer open up the audio view, instead they should toggle between the following 3 states, while also displaying the corresponding icons:
- full audio https://game-icons.net/lorc/originals/double-quaver.html
- only sfx https://game-icons.net/delapouite/originals/musical-notes.html
- no audio https://game-icons.net/lorc/originals/silence.html
This will enable track skipping by tapping A hotkey or the UI button 3 times.
Pressing Shift + A or right clicking the audio button should open up the audio view. The tooltip of the button should include info about this stuff.
These changes are in order to simplify and speed up the most used audio related actions.
