Copying a look

Assuming all your look comes from one cuelist :
Cue 3 Copy State Enter Record 5 Enter
State appears on the bottom of the touchscreen under the command line when you press Copy.

The easiest way I've found is to:

Have a group in the group palette of all the fixtures that you have on the rig and will want to copy.

Once you have the look you want to copy, on the bottom of the right hand screen you'll see a soft button "Touch",
select "touch" then select the group already recorded in your group palette.

If you've done that in that order you should have all the fixtures selected and all of their parameters.

Simply hit record cue after.

So the syntax should be:

Touch Group(X) Record Cue(X)

Both of you are in some way correct
First option will only take infos from that cuelist to create cue 5, second option will also take values from other cuelists.
If you use suck instead of touch you will also get default values into the programmer.
