Sorry.... I'm not a native speaker. My initial thoughts in the post was about why bother? Vimium and TWM is intended to non-disabled people and I used to use Acceptability to avoid mouse before discovering Vimium. So, it's a fact which Web Acceptability is good to non-disabled, but why push it when Vimium solve it? Anyways, as the first guy replied, although Vimium helps, it lacks.
