1. Load two objects
2. Put the mouse into "editing" mode. =20
3. Click "unpick" to clear the picked atom selections (if they exist).
4. To rotate, shift-left-click-and-drag on an atom.
5. To translate, shift-middle-click-and-drag on an atom.
Rotation occurs about the origin. You can change this by
control-shift-middle-clicking on any atom.
Note that if you attempt to rotate or translate while picked atom
selections exist, you will only transform a fragment.
Also note that you need to hide meshes and surfaces while performing
these kinds of transformations in order to preserve responsiveness,
since geometries are recalculated after each transformation. As of yet,
PyMOL can't do manual transformations without recalculating geometries,
but that will change. For the time being, this will likely preclude
manual docking of surfaces except with very small objects.
Also note that spheres can't be picked directly, though you can pick
lines or sticks hidden underneath the spheres.
