Action Dragger type Auto is an always available interactivity. It's completely integrated in the interactive flow, therefore it's always available. On the other hand, the Manual type provides the option Show (submenu Behaviour), to set when the Action Dragger is available for the user.
If you set the drop-down parameter Show of the Behaviour submenu with the option Always, the controller (handler) will always be shown –within the established time–, both into pause and reproduction modes.
Show only in play
In the same drop-down, if you choose the option In play the controller will be displayed only while the video is playing. As the video is paused disappear and reappear to restart playback.
Show only in pause
Unlike the previous case, if you choose on the Show drop-down parameter the option In pause, the controller (handler) will come up when the video is into pause mode and will disappear when it starts reproducing again.
