Tech Support Secrets

From http://support.wolfram.com/mathematica/kernel/Symbols/ you can access web pages Wolfram Research technical support provides for every built-in Mathematica symbol. In most cases you are linked to a web page that shows the usage message of the symbol and the full explanation from Appendix A.10 of the Mathematica Book for the selected symbol. The real value of this resource is the extra information provided for 30 or so kernel symbols. The extra information they provide about these symbols isn't available anywhere else! Unfortunately Wolfram Research does nothing to show which of the 1700+ symbols in the System context have this extra information.

I came across a lot of these pages with juicy bits of information and hyperlinks for the respective symbols are provided below.
