For the most part, I actually use Lynx to read HN. So it should be relatively easy for you to see how that feels. For added spice, you can install a screen reader like Orca and activate the "virtual braille viewer". That will give you one line of text, usually 40 or 80 characters long. The screen reader will largely follow the terminal cursor. As long as you are just editing text, that is all you need. For reading things other then around the cursor, you basically have a few buttons to move the braille display "window" around on the screen.
