Is it possible to make a precision selection tool?

I was wondering if it was possible if someone could develop a selection tool that can go on pixel level.If that didnt make sense I'll describe what it would do...hmmm...its basically the brush tool but instead of laying down color it makes a selection.I think this will be helpful for sprite artists like myself.I am well aware of the lasso tool but its just to confusing for me and slows me down and i know about the global selection option.

you could set the rectangle select to a single pixel and set the mode to additive , but then that would require a LOT of clicking
