Hi,

 a question more driven by curiosity than by the need to change
 anything.

Suppose you have the following TeX-text:

    bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla

foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats

 and because this text is so fullfilled with wisdom and knowledge,
 that no one else than you will be able to handle its contents
 carefully ;) you decide to comment it out to not to harm the public.
 As a vim newbie I would do that using block oriented visual mode on
 the first line and I-nserting a '%' (TeX's comment sign), which
 results in:

 %  bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla

% foo bar gnu gnats % bla blabla foo bar gnu gnats % % bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla % foo bar gnu gnats % % bla blabla foo bar gnu gnats

 So far so nice...it works.

 But would be there a way to acchieve the following commenting:

 %  bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla

% foo bar gnu gnats % bla blabla foo bar gnu gnats % bla blabla foo bar gnu gnats bla blabla foo bar gnu gnats bla blabla % foo bar gnu gnats % bla blabla foo bar gnu gnats

 (blank lines not commented out) by a similiar simple command like
 CTRL-v SHIFT-i <text><ESC> ?

 As said: This Q is mostly curiosity - based...I even dont know,
 whether haveing such a feature would be really useful or not.

 But as always: Experimenting is fun! :O)

 Keep editing!

1. Add all percent signs like you did above, even before blank lines.
2. Replace empty comments by blank (i.e. empty) lines as follows:

        :%s/^%\s*$//
