How do you put [code][/code] in a response?

I see other people telling new people to put their code in code tags, actually showing the [code_] and [/code_] tags in their response (without the underscore).

How do you do that? I can't figure out a way to put the tags into a response without them being turned into and?

Use [nobbc][code][/code][/nobbc] (lots of fun composing this reply).

[code]Thank You![/code]
