Unless otherwise indicated, the SQL Developer accessibility information presented here also applies to Data Modeler and Data Miner.

This topic provides information on the accessibility features of Oracle SQL Developer. It includes the following:

6.1 About Oracle SQL Developer Accessibility

It is our goal to make Oracle Products, Services, and supporting documentation accessible to the disabled community. Oracle SQL Developer supports accessibility features. For additional accessibility information for Oracle products, see the Oracle Accessibility Program page at:

http://www.oracle.com/accessibility/

6.2 Using a Screen Reader and Java Access Bridge with Oracle SQL Developer

In order for assistive technologies, like screen readers, to work with Java-based applications and applets, the Windows-based computer must also have Sun's Java Access Bridge installed. See Oracle SQL Developer Installation Guide for the screen reader setup procedure, and for the recommended minimum technology stack.

6.3 Oracle SQL Developer Features that Support Accessibility

Oracle SQL Developer provides features that are designed to support accessibility.

6.3.1 Keyboard Access

Oracle SQL Developer features support keyboard access to SQL Developer functionality; a summary is provided in this section. The following menu and toolbar functionality is provided through keyboard access:

  • Users can navigate to and invoke all menu items.

  • All toolbar functions are accessible through menu items.

  • All menus and menu items have unique and functioning mnemonic keys.

  • All context menus within the navigators and source editor can be invoked.

  • Frequently used menu items have unique accelerator keys.

The following functionality is available in SQL Developer windows:

  • Navigate between all open windows, to all nodes within a window or pane, and between tabs in a window.

  • Set focus in a window or pane.

  • Invoke all controls within a window or pane, and perform basic operations.

Tips:

  • You can press Escape to move the focus from the current dockable window to the last active editor. Press Shift+Escape to move the focus and also close the current window.

  • Colored text, underlining, or images are never used as the only method of conveying information.

6.3.4 No Audio-only Feedback

In SQL Developer, there is no situation in which the only feedback a user receives is audible feedback. All audible feedback is accompanied by a visual indicator. For example, a prompt accompanies the bell sound that occurs when an error or illegal action has taken place.

6.3.5 No Dependency on Blinking Cursor and Animation

SQL Developer makes minimal use of a blinking cursor and animation:

  • No features in SQL Developer use blinking indicators, with the exception of the cursor in the source editor.

  • No features rely on animated sequences.

The SQL Developer user interface works well with screen magnifiers. All features of the product can be magnified by a screen magnifier.

6.3.7 How to Change the Editor or Tabbed View of a File

When you press Enter on a node in the Connections Navigator, you open the default editor for that file. To switch to the different editors and views available for a document; you can use the Alt+Page Up and Alt+Page Down accelerators to invoke the Navigate > Go to Window > Right Editor and Navigate > Go to Window > Left Editor menu commands, respectively.

6.3.8 How to Read Text in a Multi-line Edit Field

To have the text in a multi-line edit field read by a screen reader, you can select text by holding down the Shift key while moving the cursor either up or down with the Arrow keys, depending on the initial cursor position.

After generating exception stack HTML links or Javadoc links in the Log window, they will not be recognized as links, but read as plain text by a screen reader. To access the links, set the cursor focus to the Log window. Right-click or press Shift+F1 and select Save As from the context menu. Save the contents of the Log window as an HTML file. Add the saved HTML file to a project or application workspace as a resource.
