How to use mouse drag gesture to position & size a still image in Premiere Pro CS6 I would like to be able to position a still image using the mouse/pointer directly on the image, to be able to drag the whole image around or resize it by dragging one of its corners or sides.

I'm sure I did this earlier but don't know which part of Adobe Premiere Pro CS6 does it. 

Sure, there's the Effect Controls but this seems to only provide for indirectly resizing and positioning the image - i.e. I mouse drag on the numbers themselves and see the effect.
Simply double click the Sequence Preview and you get handles to resize the footage and you can drag the footage around in the frame.
