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

So nothing happens when you press the escape key?

function myGUI_WindowKeyPressFcn(hObject, eventdata, handles)
switch eventdata.Key case '1' disp('Pressed key 1'); case '2' disp('Pressed key 2'); case 'escape' disp('Pressed ESC-key'); end
