During an internal discussion involving a secret plugin, an email was sent out basically giving a laundry list of training material for Office 2007. Thanks Jessica for sending out this email! I particularly like the printable article and spreadsheets!
Web-based interactive command reference guides (also available for download; follow the links in the articles to the downloadable versions)
Training courses (these also come in abridged, downloadable PowerPoint form via the “Training Templates” link my sig)
Videos (basically 5-min versions of the training courses)
Full lists of 2003-2007 command equivalents (article and downloadable spreadsheet)
An easy way to get to all of these resources to use the downloadable “tab” add-ins that put links them and some other Office Online locations right into the ribbon in a few of the products. You can find those downloadable add-ins here:
