The Programmer's Notepad is an Open Source text editor that runs on Windows. It is based on the Scintilla editng engine.

It has a similar look and feel to other Scintilla based text editors. One nice feature is a set of predefined text clips for ASP.Net, C, DocBook, HTML/XHTML, and PHP. There appears to be a way to create your own text clips. But, that documentation stub has not been completed in the help file.
