Press e to edit, and space to change what your doing. If you want to reset, press R. Sorry, no erase yet! Dark Grey is a link, Light grey is a dot that stays where you put it, and red is a dot that can move around and stuff. It's also buggy with the lines
Huge Credit to @Ricky-Jan for the physics tutorial at https://scratch.mit.edu/projects/899958937/ , you should check it out.
