Seeing the edge of the viewer when working with draw mask keyframes.

Is there a way to see beyond the edge of the viewer when you are zoomed at at 100-300%?

Working with draw mask key frames, and my keyframes go out around the edge on certain shots. Once I zoom in, I can't see past the edge of the viewer...but I need to be zoomed in in order to work the keyframes meticulously.

Is there an effects view or something I'm missing that would make working with outer edge keyframes easier?

THANKS!

I think the only way you would achieve that is to have a larger monitor or set your screen resolution higher and then pull the timeline down as low as it will go. You can reposition the image when zoomed in by dragging the red square in the rectangular box that appears when your image is over the maximum height and width of the viewer.
