• -h, --help: show the available commands with a brief description.

Once the application is launched the following keys can be used to perform specific actions:

• q: quits the application.
• r: rewinds the current video being played. Works only on videos.
• m: goes to the next media if any, or terminates the application if the current media is the last one.
• n: goes to the previous media if any, if the current media is the first one behaves like a rewind command.
• +: goes to the next keyframe. Works only on videos.
