 The built-in `gt`/`gb` sequences move to the first/last line in Normal and Visual; `gf` follows Markdown file links in Normal only. This is not a configurable general sequence prefix: bind `config.core.document_start`, `config.core.document_end`, or `config.core.follow_link` to a single key or leader sequence to add another route. A configured or disabled `g` overrides the built-in prefix in that binding mode; choosing `g` as the leader overrides it in both modes.
 
+Normal `dd` and `cc` delete/change complete rows, with leading counts. Bind `config.core.delete_line` or `config.core.change_line` to a single key or leader sequence for another route. A configured/disabled `d` or `c`, or choosing that key as the leader, overrides its built-in doubled sequence. These are dedicated line actions, not general operator–motion grammar.
