CS2 brushes: straight lines

In retouching a photo,I need to draw several perfectly straight lines.(Sailboat rigging) My freehand is not bad, but it's not great. I'm using the Brush tool because I don't know any better. Is there a way to fix points at either end and then click, like with some of the other tools? What is my best strategy? (Looks like I need a Wacom at some point.)
I've read through all 4 of my CS2 manuals without finding the answer.

The easiest way to do it is to use the pen tool to create a straight line path, then select the brush tool and stroke the path

Hi Dennis,
- Click with your Brush in the starting point
- Hold down [Shift] key
- Click at the endpoint
