# Are there any good tutorials on Boxes?

I am fairly competent in Mathematica, but I admit that I am baffled by Boxes, both making boxes and converting boxes back into expressions. I want to educate myself, but the Documentation Center is uniquely unhelpful on this subject. The examples are too contrived and bear little relation to the actual utility of creating notation. Can anyone suggest a good tutorial or more complete documentation on using Boxes to create custom expression displays and interpreting back as expressions?

• @RohitNamjoshi Interesting and informative. Sadly, it just whets my appetite more. I feel like I am missing something fundamental. Jan 24, 2019 at 20:54
