How do you locally rerender an image after changing settings

[dseal]

I learned this somewhere and forgot how I did it. I did it in the renderer window by dragging a box over the part I wanted redone. It's incredibly useful tool when you change a shader and don't need to redo the entire scene. Help.

You mean when your it renders the place that your mouse cursor is over?

It's not the mouse chasing tool. It's similar though. You can drag your mouse over a part of the previously rendered image and it redoes just that section.
