How to reproduce: hook up a Bluetooth keyboard and mouse and see for yourself

look, all helpers are saying is that it works as intended. So you're saying that a keyboard not even triggering any movement is "INTENDED"? You're telling me not being able to move the mouse is "INTENDED"? If this was "intended" then why is it that mojang fixed a bug on android where keyboard and mouse support wasn't working? And they haven't done a bug fix for my iOS device? If you're gonna make keyboard and mouse support and not make it do it's purpose, it might as well not exist. 

Please, just take a second to look at the iOS version, connect a keyboard and mouse and see. It doesn't work as intended. Hundreds of other players feel the same way. Just please fix this because it does NOT "WORK AS INTENDED"!!!
