Re: How should I modify a normal mode map set by a plugin?

Until I installed the IndexedSearch plugin, which I do really like by the way. This broke my maps which annoyed me for quite some time until today when I decided to track down the cause.

Add a plugin in your "after" directory, e.g.:

" Beware, no 'noremap' this time!
nmap n nzz
nmap N Nzz

in "$HOME/.vim/after/plugin/IndexedSearch.vim" (replace ".vim" with
"vimfiles" if you're on Windows). Files in "after" are loaded, well,
after anything else.

Best,
Paul
