I use Sublime (happily staying here as well) but I use vim still for tiny editing very now and then. I'd recommend learning just moving around (I use arrow keys). A for append to end of line, I for insert in beginning, dd for delete line, i for insert mode, wq for save and exit. Maybe 5up/5down etc for faster navigation. This is pretty much what I only use. I feel quite comfortable with vim and if I ever feel like I want to learn more, knowing how to do these super basic steps feels like a solid ground.
