I have a scanned doc that I copied onto a word doc. the scanned document text was crooked. I want to straighten the text. How do I do that

Scan it again making sure the page is not crooked in .the scanner

You would need to straighten the image with an image editor, like photoshop or pixelmator, first.

Or you could use an OCR program like ABBYY Finereader Express to convert the scanned image into a text document and then put it into Word.

If it is an image you could simply click on the image in word and then use the green dot that appears above the image to simply drag and rotate the image around. Alternatively, import it into iPhoto and use the rotation capabilities in that, click edit and then quick fixes and rotate. (Then export back into word).
