I\'ve been doing web development with Angular2 and have been using both Angular2 and Firebase to run local servers. I haven\'t been able to find a command similar to typing quit
If ctrl + c doesn't work use this:
ctrl +shift+ c
Sometimes people change the behaviour of ctrl + c for copy/pasting so you may need this.
Of course, you should also ensure that the terminal window has keyboard focus, ctrl + c won't work if your browser window has focus.
