					 It is good to group these kind off things... 
						@pieter, I find them by looking through the code.. (but that is huge). Most of them are in commons.php (guesing here, i do not have source code present) I believe. ==- I say: Keep it EZ -==

					 The reason why these vars were never listed is because of the large number of them. Nontheless I think a shorter list of only the most useful ones would be a good thing, for example: 
						
					{PHP.xk} Source key for submitting form fields {PHP.i} Iterator, often used in loops (not always) {PHP.usr.*} Various information about the current user/visitor {PHP.cfg.*} Various configuration variables  |
