Click 'SAVE' while working in a popup/CSS/JS box

It would be helpful and save TONS of time if I could click the save button while working in a CSS box or a popup box.  As it is, I need to close them every time I save, which often means I need to click 5-6 buttons to get them back open.  Just a thought…

Did you know you can use keyboard shortcuts, e.g. Command+S, or Ctrl+S ? These can be used in a popup/CSS/JS box.
