Someone posted a number of good solutions to this problem fairly
recently, but I can't seem to find that thread at the moment. As I
recall, one of the solutions used the substitute command s within a
visually-selected region to replace the selected text with that same
text preceded and followed by the desired tags. I'm not sure how
good a solution the following is, but it seems to work.
:vnoremap #3 ygvs<i><C-R>"</i><Esc>
That yanks the visually-selected text into the default register (y),
re-selects the region (gv), substitutes the text in that region (s)
with the initial tag (<i>) followed by insertion of the previously
yanked text from the default register (<C-R>") followed by the end
tag (</i>) and ends the substitution (<Esc>).
Most of the information on visual-mode is in
:help visual.txt
For a more tutorial approach, you could start with
:help toc
and search for "visual". That will show you the sections
:help 04.4
:help 10.5
:help 26.1
The commands I used above are explained in
:help visual-operators
:help gv
:help i_CTRL-R
:help mapmode-v
:help 40.1
Getting back to your statement that you didn't know how to specify a
certain number of words to wrap, once you enter visual mode by
typing 'v', you can continue to move the cursor using most of the
usual normal-mode commands. For example, to select three words to
wrap, you could move the cursor to the first word, then type
v3e
You can also move the cursor to the opposite end of the
visually-selected region by typing 'o'. So for example, after
selecting those three words you might discover that you wanted the
preceding word as well. Then you would just type
ob
Hope that helps.
