The New User Interface
As mentioned before the most noticeable difference is the new user interface. This, in turn is also the most influential. The new task bar, which takes up more space at the top of the window than before is appropriately titled the Ribbon – because, well, it is at least as thick as a ribbon, but I also suspect it is because a ribbon inherently suggests the idea of flexibility.
The Ribbon makes use of a number of contextual tabs – Home, Insert, Design, Animations, Slide Show, Review, and View – which are so designed as to make common tasks easier. For example, the presentation might already be ready as a first draft and you need to simply edit and review, then you can simply go into the “Review" tab, and all the relevant functions are available easily.
Most of the tab names themselves are self-explanatory, and the thing to remember is to realize what you are doing and move to that tab before undertaking your task. If clicking around with a mouse becomes too tedious for you, then just hit “Alt" and all keyboard options will be highlighted (for example to move to the “Review" tab, the “R" is highlighted) hitting the appropriate key at this point will take you to the required tab, and what’s more, there will be a whole set of secondary key-strokes highlighted for a specific task (in our example “C" for a new comment).
