Focusing on text input controls on cursor hover

[usser]

Hello

I think I once had a script to achieve the below but I cannot remember if it was functional or not.

Basically, I want whenever I move around the cursor in Chrome, to focus on text input controls (as if you click on them) if the cursor is hovering over such controls for few milliseconds.
Potentially, when you move the cursor away from that control, it should de-focus from that text input (but I am not sure if that will be useful).

Does anyone have any similar script to share?

Thanks
