Oh - you asked if we've ever used them in fic! Yes - I have. I made them up with the help of a latin generator.
Once again he vowed to research some silencing spells. The Insonitus charm his parents had taught him – the one they used at home when outside noises kept him awake – worked on solid surfaces, like doors, walls and windows but apparently had no effect on bedcurtains and draperies. He’d researched the Tacitus charm and thought that might work, but it was an O.W.L. level charm. The wand movement was rather complex, and the book’s description wasn’t very helpful. He’d have to ask Professor Flitwick about it after their next Charms class.
Then again, I'm of the opinion that considering the general lack of knowledge of Muggle gadgets and scientific principles, they probably have charms and spells for a LOT of things!
