vile allows the escape sequences \b, \f, \r, \t, and \n to appear in the replacement part of a substitute command. They stand for backspace, formfeed, carriage return, tab and newline, respectively. Also, from the vile documentation:

Note that vile mimics perl's handling of \u\L\1\E instead of vi's. Given :s/\(abc\)/\u\L\1\E/ vi will replace with abc whereas vile and perl will replace with Abc. This is somewhat more useful for capitalizing words.
