Hello Paul, Coot users!

In the wonderful pantheon of Coot tools, is there a way to leap between equivalent points in symmetry mates with a nice single key shortcut, for instance? Or could there be? I seem to be getting several cases with 8 copies/asu and while initially one may build a single version and then clone it into all 8 positions, at some point one gets down to wanting to check the similarities/differences of all copies, and it would be handy if I've just visiting chain A, Leu30, for instance, to be able to rapidly go to chain B, Leu30 and so on

This is not possible with symmetry mates, but is possible with NCS mates (but perhaps that's what you mean).  Press the "O" key.

 (yes, more rapidly than entering chain letters in the Go To Atom dialogue...). Similar case for

ligands...the ligand button short cut is pretty good, but if I navigate off the ligand to look at surroundings, the next click of the heteroatom /ligand center button will likely have reset to the top of the list, and with cofactors in all copies that can be 16 clicks until I get back to through the cycle.

:-) Yes.  This could be better.

You could probably make a script for "Quick View Save" and "Go To Last View" - I imagine that would do most of what you want.

In related aspects, in the Go To Atom dialog, I often have a single chain per ligand residue, but find I have to expand the sub menu to show the single residue to click on that to center. Anyway that the chain listing itself could be sensitive to clicks for centering? Obviously would be different behavior for protein chain, but perhaps the center of mass, or more simply centering on whatever is the first residue of the chain would be a consistent and desired behavior.

This is a good idea and may be very easy to add.  If it is, I'll do it tomorrow.

Paul.
