Naming conventions for controllers

I was looking at this new post on the forum and it got me thinking.

What is the best practice when naming functions that are the same across most controllers.

For example lets say I want to name a function that shows all of my users. I would call it list_users(). This function would be responsible for running the get_all function to retrieve all of the users from the database. Another might be the delete_user which would be responsible for running the model function of deleting the specific user. Any ideas on this?
