Unified access to the best community driven cheat sheets repositories of the world.

Let's imagine for a moment that there is such a thing as an ideal cheat sheet. What should it look like? What features should it have?

Concise — It should only contain the things you need, and nothing else.
Fast — It should be possible to use it instantly.
Comprehensive — It should contain answers for every possible question.
Universal — It should be available everywhere, anytime, without any preparations.
Unobtrusive — It should not distract you from your main task.
Tutoring — It should help you to learn the subject.
Inconspicuous — It should be possible to use it completely unnoticed.

Such a thing exists! It's easy to install and there's even auto-complete.
