Hmm...guess not. But, I think it would be much easier, or at least faster (for me, anyway) to use these than to copy and paste from the top.

Do we have ^sup and _sub tags?

Good suggestions ... I will clear a bit of time and get my head stuck into the forum software and see what can be done.

Ah yes...LaTeX...that's on my to learn list.

Couldn't you just zap the & literalizer? What I mean is, when I type Δ, the forum software converts it to Δ.

Well, there must be some benefit to the & literalizer. Maybe you could just check for a ; within 10 chars or so to decide whither to literalize or not.

OK, here we are, I have made the changes. Hopefully I haven't made anyhing else go crazy, but I am sure someone will let me know!

To make any of these work, put a ":" in front of the text.

I also did a trick with some of them, for example "pi" looks a lot more like pi really does (π vs π) because I used a different font for it.

Thanks ryos for the great idea.

Example usage:
π ≅ 22 ÷ 7

:pi :cong 22 :divide 7

Still laughing ... !!!

Awesome, that was really quick!
