Summary: Add white space to your Word 2003 lists, making them more readable.
Are you in the middle of writing a numbered or bulleted list and want to insert a blank line to make the list more readable? If you press ENTER, you just add another list item. If you press ENTER twice, your cursor will move out of the list, which is not what you want.
Instead, while you are in the middle of typing a list, press SHIFT-ENTER and your cursor will stay in the list and move down a line without inserting another bullet or number. Press ENTER and a new bullet or number will form. This can be useful in case your lists contain items several sentences long, as blank lines between items may make your lists more readable.
