Text Clips are a feature of Programmer's Notepad 2. They are useful for generic code that would otherwise need to be typed out (e.g for...each, switch...case, try...catch etc).
The text clips I have done are available for download. Save them in you PN2\clips folder (i.e. C:\Program Files\Programmers Notepad\clips). You will need to restart PN2 to see the new text clips.
