In the past, focus was retagged from "keyboard-focus". See: Better word for the 'keyboard-focus' tag.
I noticed some people using the "focus" tag, however, in a different way, such as visual or mental attention (which might be better tagged user-attention. This being a UX sight, with numerous people having a psych background, this is not surprising.
Should we disambiguate this tag? (It has only 20 questions.)
