2 questions: shutdown script, shortcuts 4 pos1/end
 

Is it possible to execute commands on shutdown?
is there a script where I could add to?

And another thing I was wondering about::
Is there a shortcut to jump to the beginning/end of a list?

Like when opening a file dialog (pictures), I often would like to go to the end to get to the last file. Kinetic scrolling sometime results in choosing the wrong item.

thanks
