When a library is included it is treated like a "built-in" library in the file. It is useful when you need to reference a library multiple times in one file, like when using the advanced array functions in the scripts library.
Include a library in a file:
- In the toolbar, go to Library>Include Libraries.
- In the window that pops up, click Add.
- Choose the library that you wish to include.
- Click Ok.
- Close the Included Libraries window.
