Built in formatting options
When writing a Post or a Page in the text editor, simply type in your text. The basic paragraph formatting will create itself automatically as you hit the enter key at the end of each paragraph.
For additional formatting of your text, use the graphic editing icons at the top of the Text Editor (as seen in the image below).
These icons cover many of the basic formatting functions you are most likely to use. More functions are available by clicking the advanced toolbar icon on the far right, also known as the kitchen sink. You can see this icon where the arrow is pointing in the image below.
