title: Control+Number Tkinter binding
body: <p>I want to bind a <kbd>Control+1</kbd> sequence to a window. <code>widget.bind("&lt;Control-1&gt;", lambda event: someFunction(event))</code> binds <kbd>Control + Left Mouse Click</kbd>. This is the snippet of my code that will use this:</p>
  
  <pre><code>self.master.bind("&lt;Control-1&gt;", lambda event: self.allTypeButtons[1].invoke())
  self.master.bind("&lt;Control-2&gt;", lambda event: self.allTypeButtons[2].invoke())
  self.master.bind("&lt;Control-3&gt;", lambda event: self.allTypeButtons[3].invoke())
  # self.allTypeButtons is a dictionary with Radiobuttons as its values
  </code></pre>
  
  <p>I also tried <code>self.master.bind("&lt;Control&gt;-1", lambda event: self.allTypeButtons[1].invoke())</code>, but this gives me: <code>_tkinter.TclError: bad event type or keysym "Control"</code>. </p>
  
  <p>Also, <code>self.master.bind("Control-1", lambda event: self.allTypeButtons[1].invoke())</code> and then pressing <kbd>Control+1</kbd> doesn't invoke the event.</p>
  
  <p>I know that <code>widget.bind("1", lambda event: someFunction(event))</code> binds <kbd>1</kbd>,  <code>widget.bind("&lt;1&gt;", lambda event: someFunction(event))</code> binds <kbd>Left Mouse Click</kbd>, and <code>widget.bind("&lt;Control-h&gt;", lambda event: someFunction(event))</code> binds <kbd>Control+h</kbd>, but how can I incorporate <kbd>Control+1</kbd>? Thanks in advance.</p>
