The Ribbon

The first thing you will have to get used to is the "Ribbon". It replaces the menus, no more File, Edit, View, etc. Most items are in logical locations. The main part of the Ribbon is called HOME.  The first screen shot shows the HOME tab, and also shows me searching for the word keyboard, note the column on the left, showing all locations of the word keyboard.

The FILE tab is where you can view recent documents, print, and save and attach to email. In the screen shot with margin info, you can see that it's a little easier or quicker to change margins. Here and with a lot of other things like pasting info (different formats), or changing styles, it is quicker because you can preview the changes live. The old way would be to make the change, maybe even close some dialog boxes, then see if the change is to your satisfaction. If not, you'd have to go back and try it all again. With office 2010, you click quick, "oh not good", then click the next option, "oh, better, but not good enough", click again (in the screen shot, you may click from narrow to wide margins and see changes real time).
