/a at the end as well as FARR's own PgDown will already do what you expect from +sall. I can implement +sall though if that's preferred. I'll have a look at the others.
I still want to try to improve stability (although I've never had it crash myself, but I'm not using it very often). Actually, making sure it never crashes really should be my main concern. Hearing a user say something like "I get the occasional crash but it's manageable" is certainly one of the worst things that can happen to a professional programmer
