Left and right margin positions specify the width of a paragraph of text.
Step 1
Select the text you want to change in the text entry box.
Step 2
Drag the left or right margin marker (the triangle) to the desired position on the text ruler.
Important! If the No Word Wrap command is turned on (Justification submenu in the Type menu), you can’t drag the right margin marker—text remains on a single line until you turn the command off or press the Return key to begin a new paragraph.
