Press "Recent Apps" button twice

[g_what]

I have been rooted with a custom ROM basically since day one (almost 2 years ago). If I press the "Recent Apps" button twice it will close all running recent apps. Is this a feature on stock Android or is this a feature of the various ROMs I have been using?

I ask because I just went to play with a Nexus 5 today at Best Buy and noticed this 'double-tap' feature to close all apps was not on the N5. I am trying to figure out if this feature was removed on KitKat or if it was never a feature on stock Android.

I am not aware of this option. I just tried it on my MAXX and it doesn't work on my phone.
