0) Yes, this is quite similar (although cursor movement is not quite similar
    to what human eye does while reading the book).

1) The name looks totally misleading; I suspected that such a feature was
    implemented long time ago, but it didn't come to my mind to look around
    `follow' keyword. IMHO the name should include the word `text' at least.

2) (Sorry for the huge image) This happens when I tried to search for
    `Lisp_Object' string: matches are highlighted in left window, but not
    in the right one.  Isn't it a bug?
