+//! CompletionComboBox is a subclass of QComboBox intended to have a more
+//! familiar user experience when working with auto-completion.
+//!
+//! Most notably, the <TAB> keypress is intercepted so that the tab key can be
+//! used to cycle through completion options. This is similar the behavior found
+//! in most text editors and IDEs.
+//!
+//! Additionally, the combo box is editable and uses case-sensitive matching,
+//! popup-style completion, and a "no insert" policy by default.
