I’ve started playing around with vim motions in the browser, esp. for macOS. First step has been installing the vimari Safari extension. I’ll also try the vimb. Both of the above use WebKit 2.
I’ll also check the Chrome extension Vimium on Chrome and Firefox. And probably install Qutebrowser to see how I like it. I found the list of Similar Projects on the Qutebrowser site to be very helpful.
These explorations were encouraged by this vim broswer blog post from 2017 and more recently by ‘A mouseless tale: trying for a keyboard-driven desktop’ with related HN thread.
