[Chimera-users] select by color (or other display attributes)

Elaine, that is exactly what I was looking for, and it works for selection too, thank you!
So I can make an alias as follows which will select all things (except volumes - I’m not sure what the attribute for surface color is - surfacecolor doesn’t seem to work) of a particular color, if that color is a single word - I don’t know how to supply an argument to an alias which includes spaces (selbycolor “cornflower blue” doesn’t work, for example).
alias ^selbycolor sel :/ribbonColor="$1" | :/color="$1" | @/color="$1”

I’ve saved the session for the figure, but I (stupidly)didn’t save the corresponding selections, and now I have to remember exactly what selections I used. If there was a “select by color” function, I could simply select all the atoms that are colored medium blue (or some other color ID), and change them to another color, without having to know which residues were in the original selection.
>> Analagously, it would also be handy, although less frequently useful, to be able to select on the basis of whether a residue is displayed, or represented in a particular manner - in particular, being able to restrict selection to displayed atoms/residues would be useful to avoid inadvertent modification of undisplayed models or parts thereof.
