A more intuitive norm, used in other formats, would have been :
*bold*
/italics/
_underline_
*bold*
/italics/
_underline_
The problem is that that's too many characters to reserve (they all have to be escaped when you want the actual character) making the resulting text look awful in plain text mode.
So *this* and /that/ express formatting, but not 4 * 5 nor 4*5 nor 4/5 nor m/s.
+strikeout+
~code/monospace~
_subscript
* Heading
** Heading 2
** Heading 3
- bullet
- [1/2] checklist summary
- [ ] unchecked item
- [X] checked item
I see you, mlok, you fellow person of culture :)
-strikeout-
`code`
and bloody leave "-" as a dash. I so hate that it gets transformed into a dot for "bullet enthusiasts"
