By using "nmap" rather than "nnoremap", you end up with a recursive
macro that does an "n" that does an "n" that does an "n", to infinity.

Should be able to just change it to

:nnoremap n nzz

and you're good to go.

As it appears that the intent here is to re-center the searched line, another approach is to set a high 'scrolloff' lines, like

  :set scrolloff=999

That way, even backward search (or any other jump for that matter) would also re-center the screen.

Yeah, I wondered that, but it's one of those things that I find is
nice in certain instances, but drives me nuts if it's on all the
time. Other such things are 'hls' and having all yanks/deletions go
to my system clipboard. I find that being intentional in the couple
cases where I do want such features annoys me far less than having
them on all the time.

But if the OP wants the cursor centered all the time, that's
definitely the way to go.

No need to have it on always:

function! Scoff()
let &scrolloff = &scrolloff==1 ? 555 : 1
endfun
nmap <special> <silent> <F6> :call Scoff()<cr>
imap <special> <silent> <F6> <c-o>:call Scoff()<cr>

You must not use *map without nore unless you have a clear explanation
why you prefer them. I.e. nnoremap and inoremap should be the default
always.

This best practice avoids issues like OP has. Your mappings are a
source of the problem if e.g. a user has not too uncommon `noremap :
;`+`noremap ; :` mappings that swap : and ;.

Do I understand correctly?
Always use nnoremap or inoremap
Unless recursion is desired

[Nikolay Aleksandrovich Pavlov]

Yes. I additionally suggest that “recursion is desired” should be read
as “every single key in {rhs} is being remapped” if you are writing a
plugin: this leaves only mappings like `nmap default
<Plug>(MyFooPluginMapping)` which is somewhere preceded by something
like `nnoremap <Plug>(MyFooPluginMapping) :<C-u>call
myfooplugin#function()<CR>`, so the whole {rhs} is being remapped to
something else. But this is too strict if you are writing something
for your vimrc.

That's a very succinct & correct summary. :-)
