You might think that \I and \K match non-(identifier,keyword) characters, but that is not what they do.No way for "\_i"/"\_k". "\_" already has fixed meaning: "add newline to given character class" and this change will be incompatible with current behavior.

To match non-id/non-keyword character you should use negative look-ahead: "\v%(\i@!.)+" will match one or more non-id characters.
