how to use 'define' and 'template' codes?

I'm not sure where to post this but... I'm trying to learn the advanced ropes in formatting my threads and I saw the grand list of the site's formatting codes here. 2 things that really caught my attention was the [define="it's not working?"]"define"[/define] and "template" codes. To my understanding, Define lets me hide a text that shows up only when readers mouse-over the particular word/object. And templates are supposed to be a way to easier maintain the post by setting variables. That way, by changing the template, every variables changes accordingly.

But here's the problem, I can't for the life of me figure out how to use them. Pleese Halp.

Hey delta!

You're not wrong, I believe both the codes you've tried to use don't work quite yet. I'll inform the devs about it and we'll try to fix them as soon as possible. :)

Thank so much! I thought those could have some cool implications. (•ω•)

I'm sure they could! We'll do our best to get them working. :D
