I have tried my hand at Helix, a Kakoune-derivative, but I'm immensely bothered by the selection re-drawing as I move around: it creates visual noise. When I move, I just want to move; when I act, I just want to act. The problem of "maybe I wanted to delete 4 rather than 5 words" tends to not come up often enough to demand a solution as common programming notational practice tends to establish very obvious boundaries, e.g. df= (delete to the assignment operator), dfP (delete to first capital P, where maybe I'm renaming a method getFilePath with my cursor on the character 't'), d$ (delete to end of line), etc
