This is the best Notepad replacement, IMHO.
TED Notepad is a growing freeware editor for true plain-text. It looks like a small Notepad, but is more and more fertile in innovative features, text-processing functions and other tools. All of them on hotkeys; all designed for quicker and advanced editing. The light-weight portable application fits on USB drive and loads instantly with no installation required. TED Notepad is designed especially for daily writing of notes, lists, scripts and html files.
Get ready for a simple text editor, yet full of new features and text tools - you will never learn them all. Don't type, ted it!
