1. Load PDB file
[1b. Hide meshes & surfaces; just show lines, sticks, or ribbons]
[1c. Unpick any picked atoms by clicking the "unpick" button.]

2. Select "3 Button Editing" from the Mouse menu

3. Shift-left-click-and-drag on any atom to rotate

4. Shift-middle-click-and-drag on any atom to translate

5. Ctrl-shift-middle-click on any atom to change the origin of rotation
   or use the "origin" command

6. Save your transformed structure to a PDB file.

    save test.pdb

CTRL-Z will undo the last transformation 
CTRL-A will redo the last transformation

Cheers,
Warren
