Cavern Remote user guide
Player menu

Open/close and navigate MPC-HC's menus. The top left button opens the File menu, and from there, you can navigate using the arrows and the select button in the center.
The top right button simulates the press of the Esc key, which closes the opened context menu, but can also stop playback and exit full screen.
This feature requires MPC-HC running with administrator privileges and a correctly set up CGI handler.
Playlist

Show/hide the playlist on the bottom panel, and navigate it.
OS volume

Control the operating system's volume or mute it. The feedback is in text, and there is no slider, as this might be used for equipment protection.
