Changing mask

Is there a way to move a point of a mask or change it some other way? So for example having a point of a mask and having it parented to a tracked point or keyframing it? (Or anything that would achieve a similiar effect? Preferably in Express! 
FYI: I am an absolute noob and am only editing for fun, so I hope I can find help :)

    Open up the mask properties until you find the "path" property. There will be a little grey circle next to it. Click the circle, it turns blue. Now you can move points to new positions on different frames.

    You cannot link a mask, or individual mask points to a tracked point.

    However there's a workaround. Track point. Create a white plane above video and parent to tracked point. Lower the opacity of this layer to see the video. Mask/roto on the white plane. Copy the white plane and tracked point to their own Composite Shot. Bring this Composite Shot back into your main comp, and mute/hide the embedded composite. Apply a Set Matte effect to the layer you want to mask. Select your embedded comp a Source layer and set Matte type to Alpha, Mode to Replace.
