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

but I run Matlab R2015a on Windows 7x64 the same code work with all keys except [ESC] key!!!

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
