Yes, I remember writing a VB6 driven editor. I was so happy when I got find and replace to work.

I still have the marketing page copy from 2002:

    <UL>
      <LI>Unlimited fully customizable template files</LI>
      <LI>Fully customizable syntax highlighting</LI>
      <LI>Very customizable user interface</LI>
      <LI>Color coded printing (optional)</LI>
      <LI>Column selection abilities</LI>
      <LI>Find / Replace by regular expressions</LI>
      <LI>Block indent / outdent</LI>
      <LI>Convert normal text to Ascii, Hex, and Binary</LI>
      <LI>Repeat a string n amount of times</LI>
      <LI>Windows Explorer-like file view (docked window)</LI>
      <LI>Unlimited file history</LI>
      <LI>Favorite groups and files</LI>
      <LI>Unlimited private clipboard for each open document</LI>
      <LI>Associate file types to be opened with this editor</LI>
      <LI>Split the view of a document up to 4 ways</LI>
      <LI>Code Complete (ie. IntelliSense)</LI>
      <LI>Windows XP theme support</LI>
    </UL>

Back then we used uppercase HTML tags.
