"Hi, I've emailed a few months back about this, but didn't receive much help. I was told to ask the community about it or something among those lines, but please note that this isn't some sort of gameplay thing I can fix with a setting, and has something to do with the way 1.9-latest version works.

I use different controls than the default (I use arrow keys rather than WASD, so my jump button is enter rather than space).
In 1.8.9 and lower, I can enter a command or chat message normally.
In 1.9 and higher, at the end of every command or chat message it adds in an extremely annoying jump at the end.

I've played these controls for years and it's not easy to switch, and the jump is extremely annoying- but if you're flying, it puts you in a totally new place.

Are you aware of any fix for this? I've been staying away from any 1.9+ servers because of this, and decided I'd need to give it another attempt for a fix. I'm sure it's extremely annoying for anyone with arrow key controls playing on 1.9+."

If a video is needed it can be provided, but I hope I did enough explaining.
