Substitute sign

[Rasooljafarinejad]

Hi there again,

Sometimes, when we have to write a sentence under another one with all the parts the same except for one part or two (eg. its subject), we put some sort of sign(like '') under the vocabularies that are the same in both sentences. Does it occur in English too? If so, what are this sign and the act of doing so called in English?

That's called a 'ditto mark' (or a pair of 'ditto marks') where I come from.
