Yes, using the vimium extension. My only problem is text inputs like this one, my muscle memory expects vim keys to work and I type a lot of jibberish that I have to clean up. I know there are extensions for that too but I can live with it.
I can definitely hit my Return key with more precision than I can drag a cursor over a 40x400px target but go off :P
(I use a Superior Technologies trackball because it's the only mouse I could find manufactured in the USA and it's really not very precise, it's kind of a self handicap to nudge me towards keyboard shortcuts, muscle memory gains just have a steeper curve on keyboard than mouse)
Maybe this is a physical development thing? Because i can't imagine a world in which my mouse is more accurate than my keyboard. The mouse requires two-way responsive action. I have to both move the mouse and observe the movement with my eyes to update the movement as necessary.
With the keyboard there is no such coordination, I simply think the thing i want to happen and press the appropriate keys.
