(Not a duplicate. I've checked How to "undo" SetOptions (restore defaults)? and others.)
Suppose I change some display options, e.g.:
SetOptions[EvaluationNotebook, Background -> RGBColor[0.0, 0.0, 0.0],
FontColor -> RGBColor[0, .85, .85], FontSize -> 20]
Is there a way to restore all the default display options at once, in a line or two of code, without rebooting the notebook or digging through the menus? Something like
SetOptions[EvaluationNotebook, Defaults] or a similar idea? I haven't been able to find what I need in other questions.
