title: Shortcuts to change the active tab in my application
body: <p>My application has a main window that contain a TabControl with about 7 TabItems. Inside each tabItem I put a UserControl.</p>
  
  <p>I would like that (no matter the active tab, or control) when the user press a combination of keys then user-interface jumps to a specific tab. that is, The same behavior that Firefox: alt+1 goes to the first tab, alt+n goes to the N tab.</p>
  
  <p>How can I achieve this? or... what should I start searching?</p>
  
  <p>I can't show you any code because the problem is that I don't know how to start.</p>
  
  <p>Thanks</p>
