911: Did You Know ...

... the copy-editing symbol for adding a comma to a sentence is an insert symbol and a comma, which tends to look like a little arrow?

I'm not sure many of you checked your copy-editing guide sheet to verify that, since so many people seem to be making repeated comma errors.

Also, the curly squiggle means you should delete any punctuation it touches. The squiggle looks like a little curly fry.

So if you have a squiggle connecting to a period and then there's that little arrow, what I'm trying to tell you is to replace the period with the comma.
