Ignore one "misspelling" in Vim

Question

Is there a way to tell Vim not to highlight a word once? For example, in "the password is abc123", I don't want to add abc123 to the wordlist, but still wouldn't like the big red rectangle around it.

Clarification: I'm looking for a command that makes the spell checker ignore the current word (or last misspelling).

Answer 1

Without having the word stored somewhere, it's hard (not to say impossible) to ignore it always.

But, if you are looking to ignore the word really once, that is only for a moment, you can add it to the internal list with the zG command.

                                                             *zG*
zG              Like "zg" but add the word to the internal word list
                |internal-wordlist|.


                                               *internal-wordlist*
The internal word list is used for all buffers where 'spell' is set.  It is
not stored, it is lost when you exit Vim.  It is also cleared when 'encoding'
is set.
