# SNOMED CT Concept Editor

The Concept Editor serves two basic functions:

* You can view detailed information about a concept and its various associated components (e.g. descriptions, relationships, and Reference Set members).
* You can make changes to a concept (e.g. adding another clinical phrase to describe the concept, retiring a concept or description).

In case of a SNOMED CT Concept Editor, the title of the editor displays the Preferred Term of the selected concept.

The Concept Editor displays information on a series of pages that can be selected by clicking the tabs at the bottom.

When making a change, an asterisk **`*`** appears in front of the editor's title, indicating that you have unsaved changes. Click on the **`Save`** button in the main toolbar to submit your changes to the repository or press `Ctrl`+`S` on your keyboard. Before the changes are saved, a dialog will prompt you to enter a comment describing your change.
