(Other programming languages may use the term functions or subroutines)

You may find that you want to use certain pieces of code more than once in your macro. Rather than copy-pasting the code, it would be better to give that piece of code a name, and then later use that name again to complete some sub-task, just as you do with the built-in commands Nisus Writer offers.

Note: custom commands were added in Nisus Writer Pro v2.0.
