Subject: [PATCH] Add space key functionality for playback control

Implemented handling for the space key to toggle play/pause and adjust playback rate. Introduced a timeout mechanism to increase playback speed if the space key is held down for more than 500ms. Added corresponding keyup event listener to manage playback state effectively.
