Keystroke: (F4 will select a left margin of 3 cells)
The left margin menu pulls out a list of numbers from which you can choose the left margin setting. Selecting any of these numbers causes DBT to insert a code to set the left margin accordingly. The most commonly used left margins are included. For a different number, you will need to use the Layout: Code List... dialog.
Note: If you want to insert a left margin throughout your entire document to make binding the document possible, you should generally not use the Left Margin feature described here. Use the Document: Embosser Setup dialog to set a binding margin instead.
