Proofreading options; change spaces after a sentence

[citizen53]

Is there a place where one can determine proofreading otions that correct
typing errors, and the way to change two spaces after a sentence to one?

You can have grammar check flag two spaces as an error, but there is no
automatic replacement. If this is Word 2007, click the Office button, and
then click Word Options. In the Proofing category, click the Settings button
(under "When correcting spelling and grammar in Word").
