You can't go to next field on submit, because there is a conflict when I submit with the tab or down arrow key... which is another standard behavior of forms.
Not sure if I am being clear... the change I am trying to make is as follows:
1) ANY time a control loses focus, it will submit.
2) DOWN, TAB, and ENTER all automatically move to next field.
Made down arrow and tab work with the Button Keys component on UIButtons and the selectOnTab on UIInputs. Had to tell it specifically to update on Deselect with the UI Event Trigger. Then I had to hack in that code to make ENTER work.
I have this working, but it was quite roundabout to achieve this sort of standard entry behavior... is there a more straightforward way? This is how almost all forms work.
