Replying to Line flyer trick (perfectly straight lines)

Ok, so I was messing around with lineflyer and found this really good trick to get perfect straight lines. what you do is

1. start a very very small line (where it ends is where the straight line will begin)
2. RIGHT click (so a box will come up with Settings and About Adobe 9, atleast thats what comes up for me)
3. Now, click where ever you want the straight line to end, then move your mouse slightly and you will have yourself a perfectly straight line
