How can I evaluate a script using a WindowKeyPressFcn?

MATLAB experts,

I'm using GUIDE to generate a GUI that has 5 push buttons, each of which runs a script upon being pressed. I'd also like to bind a key to each of those scripts. It seems like WindowKeyPressFcn is what I'm looking to use, but I'm not sure how to use that to make a key either press the push button or just run the script (either will work perfectly well!).

If this is a redundant question, please direct me somewhere where this has been answered, most threads I've already seen have rather complicated explanations.

Thanks in advance.

Create a single WindowKeyPressFcn callback for your figure, and have it check which key was pressed. There is an example at http://uk.mathworks.com/matlabcentral/answers/210241#answer_175778

I feel like I'm getting close. I'm just trying to do basic commands upon pushing the button to make sure everything's going through. I'm getting an error message though.

Current code:

function pushbutton1_Callback(hObject, eventdata, handles)

disp(1)

function pushbutton2_Callback(hObject, eventdata, handles)

disp(2)

function figure1_WindowKeyPressFcn(hObject, eventdata, handles)
 switch eventdata.Key

      case 'a'
          pushbutton1_Callback(handles.pushbutton1, [], handles); 
      case 's'
          pushbutton2_Callback(handles.pushbutton2, [], handles); 
   end

When I try to press a key from the GUI window, I get this:

Error while evaluating figure WindowKeyPressFcn

Error using edit (line 66)
Undefined function or variable 'hObject'.

Error in helpUtils.errorDocCallback (line 23)
            if ~edit(editTopic)

Any ideas?

Please show the line in which you set the WindowKeyPressFcn callback. Also please use the Property Inspector on the figure and see what is configured for WindowKeyPressFcn and show what it is (it might be a string)
