extract evry thing in sketchup folder.

this script already exists I used it, long ago and I try to find it.

for the move tool I know that ctrl activate the copy process but i want the copy mode activate wen i click on the move tool so the first option is copy and wen i want to move i click on ctrl

I am looking for two scripts:

the first script that allows me to select an instance of a groupe and replace it by another groupe

the second that I saw a long time ago who start the move tool in copy mode (the move tool start with the littel plus witch indicate the copy mode)
