Link directly to a specific time within a YouTube video, and other YouTube tricks

Start time

When providing a link to a YouTube video, there is a simple way to have the link open the video at a specific time within the video. Take the YouTube address (URL), e.g.
http://www.youtube.com/watch?v=jJxxHvWwQBw
and add the following to the end of this link, e.g.
&t=0m40s

Now, when you click on the link 
the video starts at 0 minutes, 40 seconds, instead of at the beginning.

Next question -- how do you make it stop after playing a certain time? I do not know of a way to do that with a simple URL parameter such as &t.

Related videos 

When a YouTube video finished, YouTube provides a number of videos it believes are related to yours. Unfortunately, you have no control over this list and it may very well include inappropriate content. To disable this screen, add   &rel=0   to the end of the URL, e.g.
http://www.youtube.com/watch?v=jJxxHvWwQBw&rel=0

Fill entire browser window

If you want a YouTube video to fill the entire browser window, replace the /watch?v=  part of the video's URL with /v/  e.g. 
http://www.youtube.com/v/jJxxHvWwQBw

Of course, you can combine all these tricks:
