For many of us, the ribbon interface (illustrated above) used in Word is a great step forward, while others find it somewhat overwhelming. If you fall into the latter category, you'll be happy to know that the ribbon can be temporarily hidden to provide you with a larger working area and clear away the clutter. How? Simple...just click one of the buttons highlighted in red below.
Remove the formatting
If text has been formatted and you change your mind about how it should appear, click the word in question, or select a section of text, and press [Ctrl]+[Space] simultaneously. If the formatting has been applied with a style, press [Ctrl]+[Shift]+[N] and it will then revert to the default style.
