During a recent plane ride, I started to read the ConTeXt manual to get a better understanding: http://www.ctex.org/documents/context/cont-enp.pdf

If anyone has plans to revise it, I have attached a file with corrections, specific comments, and general comments. I did not have the ConTeXt manual source code on hand, so I could not directly modify it.

Take the comments with a grain of salt: I have little ConTeXt experience. I hope it proves useful.

Kindest regards.
