title: How to check TWO key pressed in Matlab?
body: <p>I have a Matlab GUI with many buttons. Now I want to set some shotcuts to the button.
  Actually I can check for one button and it works fine.
  My questin is how I can check if two buttons will be press?</p>
  
  <p>Something like CTRL + KEY.
  It mustn´t the CTRL key =) It could be any key combination.</p>
  
  <p>Thanks for help.
  Sorry for my english.</p>
  
  <p>To check for one key I use this code:</p>
  
  <pre><code>key1 = get(gcf,'CurrentKey');
  
  if(strcmp (key1 ,'k'))
  %CODE HERE
  end
  </code></pre>
  
  <p>I have try something like this (for the keys k and q):</p>
  
  <pre><code>key2 = get(gcf,'CurrentKey');
  
  keystr = [key1 + key2];
  
  if(strcmp(keystr, 'kq'))
  %CODE HERE
  end
  </code></pre>
  
  <p>The value of key1 change, if you press another button on the keyboard.
  So the &amp;&amp; operator is never fullfilled.</p>
