title: How to navigate through a editable ComboBox options with arrow keys in wpf
body: <p>I have the next ComboBox:</p>
  <pre><code>&lt;ComboBox
     behaviours:ComboBoxBehavior.CharacterCasing=&quot;Upper&quot;
     IsEditable=&quot;True&quot; 
     SelectedItem=&quot;{Binding Enfermedad}&quot;
     IsTextSearchEnabled=&quot;false&quot; 
     ItemsSource=&quot;{Binding Enfermedades}&quot; 
     Text=&quot;{Binding Texto ,Mode=TwoWay}&quot;
     Style=&quot;{StaticResource EditableComboBoxStyle}&quot;&gt;
     &lt;i:Interaction.Triggers&gt;
        &lt;i:EventTrigger EventName=&quot;LostFocus&quot;&gt;
           &lt;i:InvokeCommandAction 
              Command=&quot;{Binding Path=DataContext.EnfermedadEnCatalogoCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}&quot;
              CommandParameter=&quot;{Binding Path=Text, RelativeSource={RelativeSource AncestorType={x:Type ComboBox}}}&quot;/&gt;
        &lt;/i:EventTrigger&gt;
     &lt;/i:Interaction.Triggers&gt;
  &lt;/ComboBox&gt;
  </code></pre>
  <p>All I want is to navigate trough the options with the arrows and with Enter or with a mouse click to select the item. Now the default behavior is when a use the arrows, it automatically selects the item. How can I do this? I have searched for a lot of post here in StackOverflow but no one seems to work for my case.</p>
