Why, because you had no answer? No, I simply didn't look at them. When I saw no specific page for that symbol I didn't look further. And when I thought about how I would document something I would not expect a user to enter ever, the documentation seemed quite reasonable to me. >Yes, FullForm is a fine tool, and every newbie should learn to use >it often.

I've no idea what it means for some function in Mathematica to be "properly documented". In my opinion, there is adequate documentation for Inequality. You or others may disagree which is your privilege. >This is, after all, the grand new era of bookless documentation. >Electronic means of finding information, especially those that can >be automated... like including a response to F1 for EVERY built-in >symbol... should WORK. I expect F1 or in my case, cmd-shift-f to bring up a response for any built-in symbol I would enter which as far as I know, it does. I see no reason for F1 or cmd-shift-f to bring up a response for something I would not ever expect to enter as is the case for Inequality. The only reason I can think of a user even needs to be aware of Inequality is when trying to create a pattern that matches it. For this purpose, all that is really needed is to know of its existence, something FullForm satisfies. That is, I can easily create a pattern matching an expression containing Inequality once I know it exists using FullForm without having any information as to how to use Inequality. Further, since Inequality is sequence of expressions containing things like Greater, Less etc and these symbols do bring up responses using cmd-shift-f, it becomes readily apparent what will happen if I change sub-parts using pattern matching. Again, I make no claim everything in Mathematica is adequately documented. I simply think in this specific case the documentation as written is adequate. And as stated above, you are certainly free to disagree.
