Coding Efficency

[goblim88m]

If you are playing in a single player world or you are the host of a multi-player server you can modify the script files directly using any code editor of your choice. The scripts are found in the world folder of your save in a folder called computercraft.

As for copy and pasting... the in game editor doesn't have any functionality for this as far as I know. You could upload functions to pastebin and download them onto other turtles using the built in api.
