Different methods to exit the Elixir Interactive Shell (IEx)

The article by George Guimarães focuses on different methods to exit the Elixir Interactive Shell (IEx). It covers using `Ctrl-C`, which brings up the Break command prompt, followed by entering `a` for abort. Pressing `Ctrl-C` twice has the same effect. The article also discusses `Ctrl-G` for the User switch command or Job Control Mode (JCL) where commands can be managed, including quitting with `q`. Additionally, `Ctrl-\` is highlighted as another method to exit the shell quickly, which is likened to using the abort command in Break mode but without affecting remote nodes.
