Saadani - have you tried the following? Just save the below code to an m file called KeyPressFcnTest and run it. I was able to observe the escape key event while running this code on OS X 10.9.5 with R2014a.

function KeyPressFcnTest
      close all;
      h = figure;
      set(h,'WindowKeyPressFcn',@KeyPressFcn);
      function KeyPressFcn(~,evnt)
          fprintf('key event is: %s\n',evnt.Key);
      end
end
