Autogen annotation tool question

I am using the autogen annontation tool and for the life of me I can't figure out how to delete a vegetation poly that I drew and now want to delete. How do you do this? Thanks in advance for the help.
They are hard to select. Press the select button or the (S) key, then draw a small poly around the edge (it doesn't have to cover the entire polygon) and you should see the polygon change color slightly. Then just press "DEL" and it should go away.
