Like Zoomerator this allows you to pan and scan within the current camera view. Handy when using image planes and you need to see a close up of the image plane without ruining your camera lineup.

Unlike Zoomerator it allows you to adjust it as you would tumble, track or dolly the camera in Maya.

Controls

Use LMB to zoom and MMB to pan.

Additional Controls

CTRL + LMB (click) to reset view.
SHIFT + LMB (click) to store view.
SHIFT + MMB (click) to goto stored view.
