Special 'codes' recognized by IT
I know when creating commands you can use | to 'stop' IT from doing whatever it would normally do next and I know _ is used also (to stop an automatic space?). I use these 'codes' a lot but I'm wondering if there are others I don't know about that I would also love? Is there a list anywhere? Are these the only ones? Thanks - don't know what they're called so my search was pretty useless.
