The editor area of a perspective is where a resource is created or modified.
When you double-click a resource in the WorkSpace Navigator, an editor opens. The resource type determines what type of editor is opened. For example, if you are creating a service, the Service editor opens.
Most editors initially open to the Introduction page.
Editor tabs
More than one editor can be opened at a time, but only one editor is active. Each open editor has a tab labeled with its resource name. To switch to a different editor, click its tab. If numerous editors are open, use the scroll arrows to the left of the editor tabs to view the open editors. When an editor is active, the main menu bar and toolbar display tools applicable to that editor.
Unsaved changes
An asterisk displays on the left-hand side of the editor's tab to indicate that the editor contains unsaved changes. If you are closing either the editor or the application, you are prompted to save these changes. You can close either one selected open editor or all open editors at one time. If you are closing all open editors, you are prompted to save the changes in any editor that contains unsaved changes.
