How to use an event trigger in WP8.1 with MVVM Light?

In a WPF aplication, to use a command with MVVM Light I use this:

xmlns:j="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"


<j:Interaction.Triggers>
        <j:EventTrigger EventName="PreviewKeyDown">
            <cmd:EventToCommand Command="{Binding SomeCommand}"> 
            </cmd:EventToCommand>
        </j:EventTrigger>
</j:Interaction.Triggers>

But in WP8.1 I can't use iteractivity, so I don't know how to use triggers and the EventToCommand.

Thanks.

Something like this?

xmlns:Interactivity="using:Microsoft.Xaml.Interactivity" xmlns:Core="using:Microsoft.Xaml.Interactions.Core"

<Interactivity:Interaction.Behaviors>
    <Core:EventTriggerBehavior EventName="PreviewKeyDown">
        <Core:InvokeCommandAction Command="{Binding SomeCommand}"/>
    </Core:EventTriggerBehavior>
</Interactivity:Interaction.Behaviors>

Hope this helps.
