I use the UNIX "vi" editor, but you can use any editor you like to modify the Java Script ".js" text file.
When you ask Apple's TextEdit to open files from your home directory you can press the "command"+"shift"+"." keys to reveal the hidden files in your home directory and then you should find the "Library" folder, "Application Support" etc...
"command"+"shift"+"." also works in the "Finder".
Good luck at amending or viewing your several year old filing.
