I couldn't have said it better myself!
I really like
notepad2 myself. It gives you line numbers and syntax highlighting, among other things, and handles big files better. Plus, it's free like notepad.
If you have an FTP client like CuteFtp or
Filezilla (free), you can log into your web site, right click on your file and edit it directly. Remember to always backup your file though, just in case you screw something up beyond repair (been there, done that before).
