I hate it when that happens, one time I accidentally my whole.

One way would be to use the Quick Mask function:  It's a little
button at the lower left corner of the image window:  Click once,
and your selection becomes the clear part of a transparent red
overlay on the image.

Use the paintbrush tool to paint in White on the mask, to add to
your existing selection (or make a new one).  The newly selected
area will show as fully transparent, looking through the red
overlay.  Paint in Black on the mask, to subtract from your selection.

Click the button that turns the mask on, to turn it off.  This
converts the transparent parts of the mask into a normal selection.

Here's a nice little video tutorial - but I kept wanting to click
on that button in the lower left corner of the image window when
the guy was using the Select menu to "Toggle Quick Mask" off and on!
