Quote - This is my absolute favorite. I like it much better than indent, because all of the text surrounded by the quote is indented, rather than only the line indented. It is awesome for highlighting certain points by making them stand out, and it is great for adding white space around what is being typed. The button for quotes is found between the "pre" button, and the "drop" button.
Font Type - Fonts are always fun. If anyone ever doubts, they should put a group of people in front of a word processor, and ask them to type a paragraph. Every single paragraph will have a different font type, a different color, and a different size. We each pick fonts to suit our own taste.
WdC is no different! We can choose our own font by choosing the fancy "F" button up there above the typing window. A few buttons will pop up below the line of buttons already there that illustrate the available fonts on WdC. Pick what you'd like, and type away.
Bolding, Italics, and Underlines - As you can likely tell, I like bolding things within my writing to help certain things stand out. In this case, each different format type I am displaying is easy to find because of the bold lettering. It has many other uses, however. It can be used to accent, it is often used in titles, and some even use it to make the first letter of their paragraphs stand out.
Italics and Underlines can be used in the same way. Accents, emphasis, making words pop off of a page - bold, italics, and underlines are the most used, and most useful, form of text formatting.
Oh yes! And the easiest buttons to find. They're right at the beginning.
