Moreover, what if I wanted to make it paste above (in line 8)?

Well, for that I came up with:


:9global/^\w/t.|.-1substitute/./=/g

However, I still don't understand where in that regex line it is implied to paste line 9 to line 10.

It's not entirely a regex:

:
9                     [range] for :global
global/^\w/           " for each line matching /^\w/    - :help :global
t.                    " <-- here is the 'paste'

:t is a synonym for :copy.

:copy takes a mandatory {address} argument (in this case '.' = current line for each line matched by the ':global'), and copies the lines given by [range] (in this case, implied range of "the current line"?) to below the address.

To copy line 9 in front of itself, you could do: :9g/^/t-1 (or :9t8 )

To copy lines matching /^\w/ in front of themselves: :g/^\w/t-1

...etc.
