title: Disable grabbing alt+tab in Citrix
body: <p>(I used to use NX client, which does not grab <kbd>Alt</kbd> + <kbd>Tab</kbd>, so with NX I could to switch windows with <kbd>Alt</kbd> + <kbd>Tab</kbd> on my host OS only, which is prefered for me.)</p>
  
  <p>I had to switch Citrix, which grabs this (alt-tab) keys (only in fullscreen mode) so if Citrix is active I cannot switch to any other host window (using keys), which is not preferred for me.</p>
  
  <p><strong>I want to switch windows with <kbd>Alt</kbd> + <kbd>Tab</kbd> on my host OS only.</strong></p>
  
  <p>My Citrix host is Win7, guest is a RH6. Version is 4.9</p>
