I found this very helpful and believe everyone should make the most of it if wanting to learn how to script.
Although I did come across a slight issue.

If in Musical Terms you use the terminal but then leave to the left, when you next use the terminal the gravitylines do not vanish.
The same problem in Pure Annihilation.
If in The True Test Of Scripting Abilities you have not got the first trinket and then hit the warp token you get trapped in that area forever as the gravityline reappears.
I hope that helps
