Vista - keyboard state during MouseWheel event

I want my app to scale using strg+mousewheel, just like Outlook or IE.

It is quite simple to hook into the PreviewMouseWheel to get the event,
but how do I check if ctrl is pressed down during the wheel event?

You can check the static Keyboard::Modifiers property[1]. Although you might
be able to find a more friendly way do this in WPF friendly using a MouseGesture[2].

Thanks,
((Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control))
does work like I want it to.

Mouse gesture sounds intriguing, but I found no way to check for
turning the mouse wheel in there, only for mouse click.
Since I want to scale using the same way as outlook or IE I don't want
to use ctrl+mouse movement, or something.

Thanks a lot,
Sam
