Thanks for the input, I'm just getting started trying to understand
and use your suggestions.

It's going to sound horribly lame, but I'm already stuck just trying
to call the function you wrote.
This isn't the way, I can see
:markchange <press enter> NOT

So how is it called?

Also I'm afraid I was not very clear about what I'm after. So
explaining a bit further.

I didn't expect the code to try to identify anything special in the
selected section, like an uncommented line. Just to comment it all
after asking me for Keywords.

A typical entry in a rc file with some helpful commented lines might
look like:

# helpful info
# commented value

Then I might add

# helpful info
# commented value
uncommented value

Then I would select those three lines, call my handy wrapping code
which would first prompt for keywords, then insert what I gave
it along with the commented word `Keywords:' like:

# Keywords: prompted words

then Todays date

# [todays date]

next - it would comment every thing selected:

# # helpful info
# # commented value
# uncommented value

And finally the closing symbol

# &&

So the end result would be:

# Keywords: prompted words
# [todays date]
# # helpful info
# # commented value
# uncommented value

Last step... I would manually uncomment the line I wanted:

# Keywords: prompted words
# [todays date]
# # helpful info
# # commented value
uncommented value

(Sorry if this seems a bit over the top... but wasn't able to make
clear what I was after and my example was actually incorrect too.)
