If you make your intial selection and then say you add to the selection when you really wanted to subtract, you can use Ctrl (cmd)+Z to just undo the the added part of the selecton

without losing your whole selection.

Right. but what I'm hoping for maybe needs to be on my list to Santa...to undo not my last selection, but to reverse the operation I tried to do with it.

maybe that's just too out there...

reason I ask about it is that some selections are just plain tedious to make and after 8 hours of doin' it, making a dumb mistake is just not fun.

Maybe I need me an anti-dumb-mistak-in-ator..

You might look at using channels to make selections or if your cutting out an object layer masks or paths/vector masks.

For example rather than using the lasso tool to do the whole selection, you could make a quick rough selection of the area and then use a layer mask

or channel to refine the selection.

Or if you use paths it's a lot easier to work with paths than the lasso tool and paths can be converted to selections.

OK, I'm intrigued..how can layer masks or channels be used to refine a rough lasso selection?

thank you!

R_Kelly's suggestion may be your best bet. Layer masks can be extremely helpful because you can add/ subtract your selection back and forth without worrying about getting the selection perfect the first try.

I often store selections as alpha channels to fall back on if I botch modifying selection, or if I suspect that I might want to elaborate on the selection later.

I keep the Channels Panel visible and storing a selection is a simple click on the button highlighted in this image.

Then reload the selection at any time by Cmd-clicking the channel thumbnail.

Shift, Opt and Shift+Opt modify the Cmd-click to provide add, subtract and intersect with current selection.

We've all done things like that and wished we could use the same mouse movements for something else.

My favorite misktake to make is to leave a feathering setting in the options for a selection tool (e.g., Polygonal Lasso), then go through some tedious mouse operations only to have it end up selecting a fuzzy blob... That's one of those awsh** moments.

As stated above, many folks have taught themselves to use paths so that they can use them for multiple operations or use them over again. I use paths sometimes, but sometimes I just need to select something and prefer to go directly to it.

Invariably, it turns out not to be so terribly hard to redo the work.

Also, something perhaps not mentioned... Make sure to try out the Quick Selection Tool. It can actually do a pretty good job.
