+### 2.viii Refactoring: Rename, Actions
+
+ALE supports renaming symbols in symbols in code such as variables or class
+names with the `ALERename` command.
+
+`ALECodeAction` will execute actions on the cursor or applied to a visual
+range selection, such as automatically fixing errors.

+See `:help ale-refactor` for more information.
