Hi Daniel,
Yes there is a frame drawn between each command that is on a separate line in the Chimera command file. So the crossfade you want should use commands
disp #2
movie crossfade 25
~disp #2 ; disp #3
where the display of model #3 is done on the same line, separated by a colon, after the crossfade command. You can put as many commands on a line as you want separated by semicolons. These behaviors are documented although there is so much Chimera documentation it may be hard to find.
