[PyMOL] a couple of newbie questions

Hello all.
    I am relatively new to pymol, so please excuse me if these questions 
are too simple for the list as a whole.  I am running 0.90 on a Linux 
system by way of introduction.

1)  What is the easiest way to select one molecule out of several on the 
screen and translate it independently from everything else?  I try 
selecting it. but moving the mouse while holding the mov button still 
translates everything.

2)  Is there an easy way to superimpose many molecules independently?  I 
know that I can do individual pairwise alignments, but that seems like a 
good way to let more errors creep into the process.

3)  Is there an automated way to take HET groups in a structure read from a 
PDB file and make independent molecules out of them?

Thanks,
	Andy
