Lets say you are working on an image and you spend some time making a great selection of something. You then eventually deselect and continue on with your work on the image. Lets say it really needed some work and 50 history states later your done. Or almost done. Whoops, I forgot to save that selection and now I really need it reselected to do just one more thing. Just one more i swear.
Go to your select menu and sown to reselect. Problem solved.
Just so you know I did two more corrections after I reselected, sorry.
