Last week’s techmail was Enable spell-checking in Vim and customize default behavior which talks about how to get spell checking enabled in vim. I actually wasn’t even aware that vim could do spell checking natively until a little while ago, and it sure makes for my use of it with mutt so much nicer. On the other hand, having spell checking enabled all the time isn’t ideal because doing any programming in vim will have the spell check highlighting off the charts, so this tip shows how to enable it for certain file types, and leave it off for others, so it is enabled only when you want it, and it’s out of the way when you don’t.
