title: How to get the sender of the InputBinding-Command
body: <p>I have this xaml code:</p>
  
  <pre><code>&lt;Window.InputBindings&gt;
      &lt;KeyBinding Command="{Binding Path=KeyEnterCommand}" Key="Enter" /&gt;
  &lt;/Window.InputBindings&gt;
  </code></pre>
  
  <p>and that's the Code in my ViewModel:</p>
  
  <pre><code>    private RelayCommand _keyEnterCommand;
  
      public ICommand KeyEnterCommand
      {
          get
          {
              if (_keyEnterCommand == null)
              {
                  _keyEnterCommand = new RelayCommand(param =&gt; ExecuteKeyEnterCommand());
              }
  
              return _keyEnterCommand;
          }
      }
  
      public void ExecuteKeyEnterCommand()
      {
          // Do magic
      }
  </code></pre>
  
  <p>Now is my question, how can i get the sender of this command?</p>
