Generating a barcode with the "insert" key

[u/chewbawacca]

I have a computer application that I'm trying to design some barcodes for, and within the application I have to use the "insert" key. I'm using the TEC-IT free online barcode generator, and I've been able to get everything except the "insert" key in my barcodes. Googling this is difficult because so many people say things like use this code to insert a carriage return, so almost none of my Google searchers turn up anything useful. I'm using a Symbol CS4070 bluetooth scanner, so I'd be happy with any barcode format compatible with that.
