How to disable 'Exit Full Screen' with escape on Yosemite [duplicate]

If I press Escape by mistake while working, it exits full screen mode.

I could use Ctrl+Cmd+F if I want to exit full screen mode. How can I prevent Escape key in full screen mode?

Solution 1:

Now, you could go ahead and brute-force disable the Escape key in Safari. But that'd defeat the purpose of still allowing Escape to work as a shortcut in the aforementioned places, which I'd rather avoid.
