That's how it works with most running processes.
Just open a new terminal or tab.
ctrl+c will kill the process that's running in the terminal.
Make sure when you edit the toggle script to keep in the same form using "&" and maintain spacing.
Right clicking on a file or folder and choosing copy will copy the path to the clipboard for pasting in scripts.
Then at least you know the path is correct.
PS Just looking at your last pic ....did you use "user" as your username?
