How to find documentation of hard-to-google keywords and symbols

[dnspies]

I often have trouble finding documentation for keywords such as 
"in" and "is" in D.  Also, functions like "find" I expect to be 
in std.string but it's actually in std.algorithm and Tuple I 
expect to be in std.typetuple but it's actually in std.typecons.  
These make sense in retrospect, but it would be nice to have a 
lookup table.  Further, DDT for eclipse doesn't have a 
ctrl-shift-O (auto-import), so I have to remember or figure out 
by guessing every time where to find these. The isWhite function 
I want is in std.utf, but newline is only in std.ascii.  It's a 
lot to keep track of and there doesn't seem to be any easy 
reference.

Is there an alphabetical listing (with links) of all keywords and 
functions in D?
