Refactoring Elixir code using Spacemacs or other IDEs

Anyone have any tips or examples on refactoring Elixir code using Spacemacs, Intellij or other IDE’s?

Can the community post examples with how-tos or links to blogposts that show how to quickly refactor code please?

For example:

user_allex = some_function_to_name "allex ocean"

Here, to change the word allex ocean you can place a cursor anywhere in the word and hit ca" (change around ") and then just type the new text.
