How to quickly close the edit javascript window

I have a lot of questions with javascript to edit and I'm looking for a way to quickly close the javascript window once I've edited the code. However, I find that the only way to close the window is to click the "save" button, which is inconvenient, especially when compared to how easy is to edit the question text or export tag. Is there any keyboard shortcut or faster method to save and exit the window? I've tried various shortcuts but none seem to be working.
