What Vim command(s) can be used to quote/unquote words?

Question

How can I quickly quote/unquote words and change quoting (e.g. from \' to \") in Vim? I know about the surround.vim plugin, but I would like to use

Answer 1

In addition to the other commands, this will enclose all words in a line in double quotes (as per your comment)

:s/\(\S\+\)/"\1"/

or if you want to reduce the number of backslashes, you can put a \v (very-magic) modifier at the start of the pattern

:s/\v(\S+)/"\1"/
