If you set the mouse mode to 3-button editing mode, you'll see that
Shift-Left and Shift-Middle are RotF and MovF, respectively.
So with nothing selected, if you do Shift-Left, grab an atom of a molecule
and move it, the whole molecule will rotate while all other structures are
fixed. The same process with Shift-Middle will translate that molecule
only.
If you only want to move part of a molecule, you can basically break the
molecule into 2 separate fragments with Ctrl-Middle selections. Then when
you do a rotation or translation only the end of the molecule you grabbed
will move.
The only difficulty I have with these movements is that when you do
fragment rotation you never know exactly what the axis of rotation is
going to be. Usually I have to play around with the overall camera view
and the atoms I'm grabbing a few times before I can get the rotation I
want.

[PyMOL] Re: align proteins in pymol
Dear Torin,
Thanks for your reply. However my question was not about
automatic
alignment of two protein structures. I want to move one of the structures
while keeping the other one fixed, so that I can consider alternate
alignments etc ..
So is there a way to do that with PyMOL.
thanks
krishna
