Thanks a lot for the prompt responses.
I have tried to first choice (visually select the lines and type
":normal". Works perfectly. Really easy.
I also added a visual mapping, which I didn't know they exist (pure
ignorance). Also very easy.
I am going now to investigate about the operator-pending mappings...

Once again, thanks a lot.
Cheers,
Jose
