title: Selecting an item from AutoComplete suggestion list raises KeyDown-event with ENTER key
body: <p>In Winforms I have a textbox with AutoCompleteMode set to SuggestAppend and a AutoCompleteCustomSource set. When the user types some letters the suggestion list is shown. If an item of this list is selected by clicking it with the mouse, the KeyDown-event of the form containing the textbox is raised for the ENTER key.</p>
  
  <p>Is there any possibility to NOT raise this event when selecting a suggested item with the mouse?</p>
