Hi, (I have posted these in Unity 5.3 beta forum too, sorry for 2x) Backspace bug was fixed in 5.1.3, but now it is here again. (700861) - WebGL: Fixed backspace key navigating away from page in Chrome. Please fix it in the next beta. I have used SetNextControlName for Tab button, but it is working only in Unity editor. Please fix it in the next beta. I would like to use Enter button in the browsers after I have used the last inputField. If it is possible, please fix it. Thanks for all.
