When you draw a regular line using shapes, and you want to move one end of
the line to straighten it or move it around, you can move it back to being
straight or in small increments.
In Excel 2000 and 2003, when you used your mouse to grab and move the end of
the line, you could hit 'alt' at the same time and it would help you to move
the line in small increments. This does not work in Excel 2007. The end of
your line just jumps around.

Anyone able to help? Thanks.
