Most of the reference is directly accessible in shorthand so instead of:
http://cplusplus.com/reference/stl/queue/
You just need to write:
http://cplusplus.com/queue
This works with every C and C++ function I've needed. Doesn't seem to work with C headers (stdio.h/stdio doesn't work) but
http://cplusplus.com/cstdio
works.
Nifty.
The thing I like about this site is that it has so many features and sections, yet the directory paths are still understandable.
