a question from the techno-challenged

[oaktavia]

I use Word for Windows - while not paying attention (it was late, I was tired, and bleary-eyed) I accidentally hit "Add" to a word on the auto spell check thingy... (ya know the one that shows up with a red squiggly underline..?) and it added it. This morning while proof-reading it, I discovered I saved an incorrect spelling.

Where do I find the file/folder of saved/added words...? and -
How do I delete/re-enter the proper spelling?

thank you, thank you, thank you, thank you!!!!
