Useful when you need to say or think multiLine stuff. Make sure that you understand javaScript in "Notes and Credits" before running it because you can't trust me.
// I used this javaScript: var y=Array.prototype.join; Array.prototype.join=function(){ if(this[0]==="magic"){ this[0]="\n"; // you can change "\n" to any string Array.prototype.join=y; // restore Array.prototype.join() } return y.apply(this,arguments); }; // Create a list ["magic"] in scratch. // Run this script using javaScript console. // Run the ({list name here}) block.
