Commaet(s). & is Et, which means "and" in latin. Your read of it reminds me of the old Jack in the Box signage which, according to a good friend, looked like "Jack in the B-Fish"
And just for compl&eness the symbol "&" is called an ampersand.
I think "comma_nds" ("commands" if you remove the underscore) makes the pun mkre obvious.
I didn't get it at first thought, thinking of the .nds file extension for Nintendo DS ROMs.
The pun still holds as "comma,nds" though, and might even do so better.
Oh, I thought the user was suggesting using just ",nds" instead of "comma,nds". That makes more sense.
Oh, they might have been. The joke might have gone completely over my head when I said that! Still though, it sounds like "comma,nds" would be a good compromise either way.
