In Word 2003 I was able to right click on a line and choose 'edit points'.
This would allow me to add and edit multiple straight and/or curved points to
the line in order to change it's shape so that I could mimic a less than
straight line in a picture.

In 2007 I've figured out that I can insert a shape and edit its points, but
it won't let me do the same for a straight or curved line. This is creating
more work for me, as it is difficult to edit the points from a shape into a
line.

In 2007, is there a way to edit the points of just a line?
