how do i do this:

[[[Say] Hello]], [[[Ignore]Mr.Dot]]

to print:

[Say]Hello, [Ignore]Mr.Dot

without it saying:

" role="link" tabindex="0">

also with **

I can't find the code that parses the text, so I don't know if there's any kind of escaping supported. But the easiest way is probably to use HTML character entities.

• If you enter & or & it will appear as &
• If you enter * or * it will appear as *
• If you enter < or < it will appear as <
• If you enter > or > it will appear as >
• If you enter [ or [ it will appear as [
• If you enter ] or ] it will appear as ]
• If you enter { or { it will appear as {
• If you enter } or } it will appear as }

(The numeric ones are standard ASCII character numbers. The names are mnemonics which are supposed to be easier to remember, but they were introduced at different times so might not all work in older browsers)

Note that you can't use these in section names; it doesn't seem to work. So you would need to use separate link text. Something like:

[[[Say] Hello]](say hello)

[[say hello]]:
This is the section that the link leads to.
