title: KeyPressFcn in Matlabs App Designer
body: <p>Hey there great ppl out there!</p>
  
  <p>I have a rather simple problem but no idea how to solve it. 2h Google search didn´t help.</p>
  
  <p>I´m getting hands on Matlab´s App Designer.</p>
  
  <p>To keep it simple: I have a button and a numerical field. Every time I click the button - a callback is called increasing the value of the numerical field by 1.</p>
  
  <p>How can I implement a KeyPress event?!? I.e. When I press the '+' Key on my keyboard I would like to trigger the callback fuction of the button (or if not possible any other function). </p>
  
  <p>I´m pretty sure the developers of App Designer must have thought about this - but I´m simply to untalented to find the right documentation. I think in GUIDE there´s something called 'keypressfcn' - so I basically need an equivalent for the App Designer.</p>
  
  <p>Please help :)</p>
