I've never really liked ZZ, for no real reason. I get an error with it
saving an edited read only file, just like :wq (sudo or not) and :x

E45: 'readonly' option is set (add ! to override)

So I reckon that :x! is the winner.

:set ignorecase smartcase

Then if you do a search in all lower case it is case insensitive. If
there is an upper case character in the search string it is case
sensitive. Better is to prepend \C (match case) or \c (ignore case) to
your search string. This ignores the value of ignorecase.

So, if you're searching for foo, FOO, foO then your search string is


If you're searching for foo, but not FOO, the search string is


This is all from the vim help file usr_27.txt by the way, I didn't
know it before (so thanks, it was useful).
