How set set multiple color columns / cc (:set colorcolumn) in vim?

Question

A single colorcolumn can be set like this:

:set colorcolumn=80

How can I set multiple colorcolumns (e.g., at columns 40 and 80)?

Answer 1

Use commas as delimiters to specify multiple columns, e.g.,

:set colorcolumn=40,80

-or-

:set cc=40,80

will set two colorcolumns, one at column 40 and one at column 80.

Also, += and -= can be used to add/remove columns:

:set cc+=60
:set cc-=80

will add column 60 and remove column 80, so the columns will now be 40 and 60.
