First thing you should check is that such behaviour is not triggered
when you press `s` when Vim is launched using

vim -u NONE -i NONE -N

. Second is the same thing, but with `-u NORC` (`-u NONE` disables
sourcing anything, including vimrc and plugins, NORC disables only
vimrc).

After this check what `verbose nmap s` reports: it normally should
report "No mapping found". `verbose` will tell you where the mapping
is defined if the problem is some mapping using `s` key. There is no
need to configure `s` command: you can use mappings to replace `s`
command with *any* other command or command sequence with any
behaviour.
