Word offers lots of types tab that you can use. One of those types are decimal tabs. If a tab is a decimal tab, Microsoft Word aligns the text is aligned according to a decimal point or full stop in the text.
You would most often use decimal tabs to align columns of numbers but you can use them to align anything that contains a full stop.
If the text does not contain a fullstop, Microsoft Word right-aligns to the tab stop. If the text contains two full stops, it alignes based on the first one.
Once you set tabs, they appear on the ruler underneath the measurement markings. You can quickly adjust tab stops by using your mouse to drag the markings to a new location on the ruler. Simply point to a tab stop marking with the mouse, click on the left mouse button, and drag the tab stop to a different location. Release the mouse button when you are satisfied with the new tab location.
