TSynEdit? TSynPosSyn (position highlighter, see examples)

You can remove all the SynEdit.Keystrokes. And also set it to not react 
to mouse, if required (use MouseActions and make them empty)
You can also set the caret shape, to be a block (full char width).

If you want to loose ballast, you can remove various of the "Markup"
