My life is split between Emacs (no mouse usage at all), terminals (no mouse usage at all except the occasional copy/paste... but typically I'll use commands for this, including a nice "pipe into Emacs" pipe I found online) and then browsers.

Ah, browsers. I didn't bother (yet?) trying to set up a mouseless browser experience because the Web was built by people who obviously love their dear mouses (apparently the plural of mouse is either mice or mouses). And I didn't bother trying to integrate my browser into Emacs either. I'm not that rad.

So I'm in two worlds at once: the mouse world when browsing and the keyboard-only world when terminal'ing / Emacs'ing.
