Note: AC have been changed since using ctrl+shift+<key> was a bad idea, since most browsers override these shortcuts for other actions
1. Add shortcut for toggling play/pause: Ctrl+Shift+P
2. Add shortcut for muting audio: M
3. Find a way to inform the users about the shortcuts when they enter the Interactive Video.
- A good way of doing this could be to include the shortcuts as a Tooltip on the buttons.
Currently 'k' toggles play/pause.
