Outlook 2007: Email Zoom Facility

Somehow I must have accidentally clicked a button somewhere because suddenly my compose email screen was enormous - as if magnified by 100%. Clicking around various buttons on the 'ribbon' I couldn't seem to find the answer. Thanks to "The How-To Geek"  I found the solution. Useful facility to be able to turn on if you are becoming short-sighted.....

1. Click on Format Text
2. Click on zoom
3. Choose your level of zoom then click 'ok'
