I got the important parts of my IsarToLatex markup language

after all, to prove things, not just mess around with software.
The basic idea of my humble man's WYSIWYG is:
1) Create markup delimiters by subscripting or superscripting select ASCII or
2) in non-standard ways,
3) that make the symbols smaller and more discrete,
4) but yet you can still recognize them and not confuse them for similar
looking characters, even when using a small font.
Interesting what can be done with a few control symbols. It appears to be
generally in line with the "markdown" family of tools. Do you have your
own implementation somewhere on the web?
I would have never got the idea to make a subscripted ASCII prime. Such
things depend a lot on the actual font being used, though.
There's a jEdit screenshot for people who can't or don't want to load
The screenshot shows some of my markup characters, and I'm using a size
10 font. The spellchecker is underlining some things.
Which spellchecker are you using here? Are you satisfied with it? At some
point I would like to wire-up a reasonably good one with Isabelle/jEdit in
a way that it knows about the formal vs. informal parts of the text. So
it won't hilight the formal option "SAT4J", for example.
As to generating other THY files from a working file like sTs01.thy,
such as a THY that ASCII lovers would find acceptable and useful, that's
a future possibility, but not to be done if unnecessary. These days,
most people don't expect HTML pages to be converted to TXT files.
At some point I would like to see the Isabelle/Isar sources rendered
nicely in HTML, based on similar pseudo-markup symbols as you have here,
or like a variant of Markdown that is using non-ASCII characters.
Luckily Isabelle has an infinite amount of \<foo> symbols to play with,
and they can be assigned to Unicode glyphs on demand.
