# Workbench integration with Web editors

There are several editors for use in various contexts for various file types. To edit a file using its default editor, double-click on the file name in the Project Explorer view, or right-click on the file and select Open. The editor that is last used to open a file becomes the default for that particular file. To edit the file with a different editor, right-click on the file and select Open With to choose from a list of available editors.

In the workbench, you can associate file-name extensions for different types of resources with various editors. A resource extension can have more than one editor associated with it; the last editor used for a particular extension type is indicated by a black dot before it in the Open With pop-up menu. You can associate extensions that are known to the workbench with additional editors, by using the File Associations preferences page, accessed by selecting Window > Preferences > Workbench > File Associations.

The Properties view provides general capabilities that are advantageous to Web editor users.

Properties view
  The Properties view (Window > Show View > Properties) contains a list of attributes and editable attribute values. For example, when you select an image tag img , the width and height values appear for editing. In addition, any other attributes allowed by the standard specified in the DOCTYPE for the file (such as the HTML 4.0.1 DTD) are listed. When you click the value column of a property, you can select from among the list of available attribute values.

  The pop-up menu in the Properties view enables you to undo, cut, copy, paste, delete, and select all. The options that are available at a given time depends on where the cursor is located when you right-click to display the pop-up menu. To see the pop-up menu that contains undo, cut, and so on, the property value field must be active. (This is accomplished by selecting the property and then selecting its value.) Otherwise, the pop-up menu will contain different options.

  Use the Restore Default Value button to change any value back to the default setting.

  After you are in the Properties view, you can modify other property values for specific tags. To edit another tag using the Properties view, move the cursor within the editing area of the Source page or Design page to the tag you want to edit. The appropriate properties and values are displayed in the Properties view.
