variables

Here's how to show, set, and reset vim's variables:

:set - shows vars different from defaults
:set all - shows all values
:set foo? - shows the value of foo
:set foo! - Toggle (Invert) the value of foo
:set foo+=opt - add opt to the value w/o changing others
:set foo-=opt - remove opt from value
:set foo& - reset foo to default value
:setlocal foo - only the current buffer

:verbose set foo? - tells you where it was last set!
