Brush tool in a straight line

[mercphoto]

I know there is a way to do this, to set a brush point at one place, then select an ending point, and Photoshop will draw a line with the brush straight from one point to the other. I just don't know the way to do it. I'm using CS3 on a Mac. Thanks.

Click with brush at first point, Shift-click at second point.

You could also click a straight path segment with the Pen tool and apply a stroke to it, but that's more work.

You can also use any of the selection tools and use the fill command (shift+F5).
