Thank you, that's nice. I still see superior adding a new command 
for 2 resons.

- I like to provide the binding by default to the users; same as we do 
with `n' or `p' to navigate the matches without selecting the buffer.  It 
is quite convenient.

- The hook above doesn't accept a prefix.  With the original proposal I 
can do:
2 l ; scroll the current displayed match at the second line.
This become handy when you want to inspect the context of the match.
