How to use an accesskey on a WPF Button with a custom ContentTemplate?

Question

Scenario:

Currently I have this XAML code:

Answer 1

Instead of TextBlock use AccessText thus:

<Button Content="_Cancel" IsCancel="True" Command="{Binding Path=CancelCommand}" Margin="5">
   <Button.ContentTemplate>
      <DataTemplate>
         <AccessText Margin="10,0,10,0" Text="{Binding}"/>
      </DataTemplate>
   </Button.ContentTemplate>
</Button>

PS. ContentPresenter should be used inside a ControlTemplate to display content according to a DataTemplate. If you use it within a DataTemplate it causes infinite recursion as the DataTemplate is invoked over and over again.
