How do you insert literal control characters in vi on Mac?

For example what is the Mac equivalent of

Unix ^V^M Windows ^Q^M (in vim)

to insert a \r into a substitution string?

Solution 1:

It's the same like in Unix/Linux:

^V^M

But, if you want to use the character in a substitution string, then you should write it like it is, \r, e.g.

:%s/blabla/\r/
