Q:

Disable Escape key in Safari for getting out of full screen mode

I use Safari in Full Screen mode on OS X Mavericks all the time.   I also use the escape key in web pages fairly frequently for various things (depends on the webpage). 
One unfortunate side effect of these two facts is that I will occasionally turn off Full Screen mode inadvertently by hitting the escape key on a page that doesn't intercept the escape key. 
Is there a way to disable the "Escape turns off full screen mode" behavior in Safari? 

A:

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. 

See here for an example to remap Escape to ⌥Escape with a Keyboard Maestro macro:
