Button select all/de-select all

When we click on Select Documentation, it would be nice to have a button which de-select all docs directly.
Thank you for your work !

I've considered adding a select-all button a few times, but I fear it's going to encourage people to select more docs than they really use, and they'll end up with a slower / nosier search.
Maybe I'll do this as part of #4 but for now I don't think we need a button.
Thanks for the suggestion though!

I understand the problem for a select-all button but if for example I want only the C++ documentation, i need to de-select CSS, DOM, DOM Events, HTML, HTTP and Javascript because they are selected by default.
So, a button (only) "de-select all" would be very useful...

Oh, I see. I don't think it's worth adding a new UI control just to de-select the default docs — sorry. You only need to do that once per browser.
