My keyboard is currently going through something weird or the software for it. It's a Razer Cynosa Chroma keyboard, and I didn't have a problem with it at first. This only started about 3 weeks ago and I was just dealing with it. Pretty much my problem is that my up arrow key works but at the same time it types a 5. My down arrow key is also associated with the End key, and I'm not totally sure why. I've asked a question about this on another site, but one answer just says it has to do with a modifier know as the 'Fn' (Function) key, and need to hold it down while using the key. I'm not totally sure how that works honestly. If anyone knows a solution to this, it'd be really appreciated. Thanks.
