Overview of Application Accessibility

The application is designed with accessibility features that support assistive technologies, such as screen readers. You can use the General Preferences: Accessibility page in the Set Preferences work area to set the accessibility modes of the application. For more information about Oracle's commitment to accessibility, see http://oracle.com/accessibility.

Keyboard Shortcuts

You can navigate the entire application without a mouse and access all relevant functionality using only the keyboard. You don't need assistive technology to use keyboard-only navigation, which is available to all users. Keyboard shortcuts enable you to perform user interface actions without using a mouse. For example, you can use keyboard shortcuts to save a file or open a tab. Keyboard shortcuts for specific UI elements come from the Oracle Application Development Framework components that they're based on. You might also find keyboard shortcuts that are specific to a particular feature or product.

Accessibility Features

You can use assistive technology products, such as screen readers, while you work in the application. Certain components render differently in the screen reader mode. For example, date fields in the default mode have a date picker. You can either use the date picker to choose a date, or manually enter the date as text. In screen reader mode, you only enter information as text because date pickers aren't available.

You can also use a keyboard instead of a mouse. Some of the accessibility features discussed here are:

  • Skip navigation links

  • Additional role and state labels

  • Isolated display

  • Content change announcements

  • Alternatives actions to drag and drop

Skip Navigation Links

When you access a page and press the Tab key, the Skip to main content link appears. Use this link to skip the global header and navigate directly to the filmstrip, which is the row of page entry icons before the page title.

Additional Role and State Labels

When you access a page in screen reader mode, the screen reader reads the labels of various user interface components such as menus and buttons, including the role and state labels. These additional labels identify the purpose and current state of the item. In some cases, the Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) standards are leveraged for role and state information.

Isolated Display

In screen reader mode, when you open a menu or a dialog box, the display is isolated on the open component until you close it. For example, when you open the Actions menu, only the Actions Menu heading and menu items are displayed. In addition to the menu item names, the isolated display provides contextual information for each item. For example, each item has Menu Item or Menu as a suffix, with the latter identifying submenus that you can open. For dialog boxes, the isolated display also provides additional information, for example to identify fields with invalid data entry.

Content Change Announcements

In screen reader mode, WAI-ARIA live regions announce changes to the application. For example, when you open or close dialog boxes, you can hear the rendering of partial content, progression of progress indicators, or changes in the menu and dialog box state.

Alternatives to Drag and Drop

Pages that provide drag and drop operations also support alternative methods of operation.

In tables where you can use drag and drop to move columns, you can select Reorder Columns from the View menu, and move(or change) the order of the selected items.

Keyboard Shortcuts

Keyboard Shortcuts for Oracle Application Development Framework Components

The application is based on Oracle Application Development Framework (ADF) components which come with standard keyboard shortcuts. In some cases, you might find different keyboard shortcuts specific to the page, feature or product that you're using.

Oracle ADF keyboard shortcuts are described in the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework.

Default Mode

Screen Reader Mode

The keyboard shortcuts for some components in screen reader mode are different from the shortcuts in default mode.

Keyboard Shortcuts for Infolets

You can use keyboard shortcuts to operate the infolets on the home page or specific work areas. The shortcuts might be different from the ones listed in the following table depending on the selected infolet.
