Where to look in laravel documentation api for all available functions for each facade?

I know how facades work and I can find full facede list in Laravel: http://ift.tt/20ZoUfM

But how I can see all available functions for each facade ?

If I use facase Session I can: 1.Find methods in laravel documentation: http://ift.tt/1S5PR10

2.Or search methods in each class in "Illuminate/Session" namespace http://ift.tt/20ZoVQO

But I think it should be more elegant to find ?
