????
*Which* commands do you mean, specifically. There are no controls for movies on
the right-click menu.
If you mean the Browser's right-click menu then this is coded into the browser
application so the answer is No.
If you mean you want a media player buttons to control a movie, then use the
plugin from Insert > Web Component > Advanced to choose the plugin relevant to
the movie file format.
If you mean specific right-click menus in different applications, like in an
image editor or movie player, then No, they are specific to those applications.
Can you explain in more detail what you mean?
