I found myself trying to remember how to right-justify part of a line in Microsoft Word again.
If the ruler isn’t visible at the top of the typing area, select Ruler from the View menu. Create a tab stop by clicking on Format | Tabs. In the Tab stop position field, enter the inch number on the ruler (6, for example) where the right margin begins. Check the Alignment option titled Right, select a Leader character if you wish, and click on OK. This will result in the effect you want.
On each line, type the item name, press the Tab key, then type the issue date. All the dates will line up at the right margin. If you’re applying this formatting to text that’s already typed, select all the text before you set the tab.
