At least one perspective must be open to contain the Musical Score View. As soon as an MEI Object has been created or opened, the view will appear. In this area the musical scores that you can open from the TextGrid Repository, or create and modify with the Palette and the Outline View, will be displayed. The encoded note text is displayed in a WYSIWYM View to display the encoding properly. All changes in the document can be made in this WYSIWYG-style. The Score View is primarily meant for the two-dimensional display of the rendering, as drag & drop operations are disabled. Elements in the note sheet should be modified with the assistance of the Editor’s Palette and the Outline and Properties View . Single elements in the Score View as notes or rests can be selected and appear in blue by left-clicking on them. More complex interventions in the source code of an MEI document will require the XML Editor. To open the source code of an MEI Object, please use its context menu in the Navigator and choose “Open with > XML Editor”. The context menu is enabled on the Score View, but direct user manipulation via drag & drop is disabled. It offers the following options: "Run as > Run Configurations…" opens a new window. There the user will be able to create new configurations for the launch and define the settings. You can validate your MEI document by clicking “Validate”. Use some Eclipse-specific options by selecting “Team”, “Compare With”, or “Replace With”. To save your changes, click
