What about "set cartoon_color" to control the color of the cartoon to
show for the backbone? This is completely separated from the atom
colors. Alternatively, you may colour everything the way you want for
the atoms and then color the c-alpha atoms otherwise (which control
the cartoon color). The difference with the first approach is that in
the latter the bond with the side chain will be partially coloured as

You can create distance objects to show these things... have a look at
the command "dist". Particularly useful with the selection statement
"x within r of y".

You can "disable" an object (which also hides it from view) or you can
"mask" a selection, which makes atoms "unpickable". There's also the
command "protect". Have a look at the help files for these.

No. There must be a "movie.py" around somewhere, written by Kristian
Rother and edited by myself, which contains handy movie-making
