Polygon Lasso tool for Photoshop online

Joe, I’ve never used it, but was interested to try.  The lasso tool appears to be free hand only although we can constrain it to be perpendicular to the boundaries by holding down the shift key.  Ctrl and Alt have no affect AFAICT.  I was impressed by the Quick Select tool which works like the magnetic lasso tool but 100 times better.  It selected a person on a busy background remarkably accurately and smoothly.  A highly useable tool.  I am sure they would have included the ability to link points with the Lasso tool if it was doable, and this is a highly cut down convenience app after all.
