Is it possible to setup "CTRL+C" as a shortcut to run a GUIDE Pushbutton callback? I'm using eventdata.Modifier (for CTRL) and eventdata.Key (for C) in KeyPressFcn like below:

if strcmp(eventdata.Modifier,'control') && strcmp(eventdata.Key,'c')
  pushbutton_Callback(...)
end

The problem is that when I hit "Control", both "Modifier" and "Key" fields of "eventdata" set to "Control" as long as CTRL is pressed.

example:

if ~isempty(eventdata.Modifier)

if isequal(eventdata.Modifier{1},'control')

%%% uncomment next line to identify new Ctrl+ letter code

% double(eventdata.Character)

if double(eventdata.Character)==26

UndBf(hObject,eventdata,handles);

end

I just noticed that the ctrl modifier prints an invalid character (square shape) and this invalid charcter has distic value, after transformation to double, for each key. So...
