Task queries for tags and future days

Where is the current syntax list for :inputs like this? I am using on of your advance queries from another thread and it’s working exactly as needed.
I have a page repeating the same query but iterated into Today, Tomorrow, +2, +3 days but I want to add a “everything after 7 days away” query to the list but can’t get it to work. I read somewhere that the

:xd-after

syntax was deprecated
