Straight lines with Ink in slide show

[GeoTol]

In earlier versions of PowerPoint I was able to hold down the shift key in
the show mode and get straight lines. That was fantastic for making boxes,
How do I do this in PowerPoint 2003?

Adding the motion path

Now we'll add the motion-path animation to complete the effect. With the
object still selected, return to the Custom Animation task pane and choose
Add effect » Motion Paths » Draw Custom Path » Line.

Your cursor is now a crosshair shape, and you can draw the line from the
beginning point to the end point. If you want to constrain the line to
15-degree angles, press the Shift key as you draw. This is a helpful
technique to ensure perfectly straight lines.
