- Type the number or alphabet followed by a period (dot) symbol.
- Press the tab button after the period symbol
- Type the content of the first line (optional) and press enter key.
That's it. Now you will find the list starting with the number or alphabet you typed over there. Shown below is a sample list created using the above steps.
In addition to that, a little research on the subject helped me to prefix the list numbers with a custom text, as shown in the image below.
