You can move the first line of selected paragraphs in block text to the left or right of the left margin by changing the first line indent. If you select a text object, the first line of each paragraph separated by a return is indented. If you highlight a portion of one or more paragraphs, only the first lines of those paragraphs are indented.
A positive indent moves the text toward the right (away from the left margin); a negative indent moves the text toward the left (inside of the left margin).
