A blank document in outline view, awaiting its first entry.
To organize your ideas from scratch, start with a blank document and switch to outline view: click Outline on the View menu.
A "minus" sign appears in the upper-left corner of the document, along with a blinking insertion point. This is where you'll enter your first top-level outline heading. The minus sign indicates that the heading does not yet contain any subheadings or subordinate text.
When you switch your document to outline view, you'll also notice that the Outlining toolbar appears, which you can use to manipulate the outline as you work.
