It's looking like a major part of my summer project this year will be
working on ways to select and move groups around and get them back together
again. Good to see interest in this; please let me know if you are
particularly interested in this and want to contribute ideas, programming,
I agree that it has loads of potential for visualizations that are basically
heretofore unheard of. This should be fun!
To get us started, I've checked in some changes in both Jmol 12.1 and 12.0.
CTRL-Z (undo) and CTRL-Y or CTRL-SHIFT-Z (redo) should work now in both
versions. These I originally set up for the model kit, but this is a great
application of them as well. Say you move atoms around using
set dragSelected; set allowRotateSelected // so rotations and dragging
[rotate and move chain A using ALT-LEFT and ALT-SHIFT-LEFT (respectively) as
much as you want]
Pressing CTRL-Z repeatedly restores up to 100 steps, and CTRL-SHIFT-Z or
CTRL-Y takes you forward.
