Then / form of search terms to quickly locate find, easy to flip
After entering the paging state less you can use the command:
- / String: Down "character string" feature
- ? String: up search for "string" feature
- n: a search before repeating (and / or related?)
- N: a search (and / or related?) Before the inverted repeat
- b back down one page
