Adds much-needed and much-requested keyboard shortcuts to go to the next section in a course.
This is a simple, non-jQuery script to add a much-missed keyboard shortcut back into CodeSchool. In the past, Alt + J proceeded you to the next exercise without having to use the mouse to click the button. For some reason, this useful feature was removed. Here it is again, recreated as a user script for your enjoyment!
If you have any concerns about the safety of this script, please read through the code to see what it does. It's not malicious by any means. Also, if you want to use a different key combination, feel free to copy and modify this script.
Please leave feedback if you have any questions, feature requests, or bug reports.
