Digitisation with OneNote

I recently discovered a useful feature in OneNote (part of MS Office 07) which allows the extraction of text from images. This was always relatively easy for pdfs created from Word, TeX etc, but apparently OneNote uses OCR (Optical Character Recognition), same as the Gardai have on their traffic cameras, allowing you to select text from images such as faxes, pictures, and scanned photocopies. Handy for digitisation.
