Comment about WordStar and Markdown by codingdave:
(I don’t have an account there so I’m writing here.)
I was using WordStar for CP/M. Since then I’ve been away, but I’ve been observing WordStar for Windows a bit.
For CP/M and MS-DOS:
a. When editing a style and text, shows marks (which are visible symbols).
b. When editing text, hide the mark and indicate “that’s where the style is” in ways that can be shown on the character display, such as underlining or inverting.
a. When editing a style and text, shows marks (which are visible symbols), same as old days.
b. When editing text, hide the mark and WYSIWYG (What You See Is What You Get) view.
I imagine codingdave is saying that WordStar’s 2-mode for Windows is “necessary and sufficient”, so no new method (like the Bike’s Typing Affinity) is needed.
I myself can say that “Typing Affinity” and “Visible Typing Attributes” are quite good solutions because they can express WordStar’s two modes in one mode without showing the marks inline.
(OK, I’m sorry if it’s all misunderstood… )
