C Keyboard Shortcuts

This appendix describes the keyboard shortcuts that can be used instead of pointing devices.

This appendix includes the following sections:

C.1 Introduction to Keyboard Shortcuts

Keyboard shortcuts provide an alternative to pointing devices for navigating the page. There are five types of keyboard shortcuts that can be provided in BLAF Plus applications: Tab Traversal, Accelerator Keys, Access Keys, Default Cursor/Focus Placement, and use of the Enter key in certain contexts.

There are five types of keyboard shortcuts that can be provided in BLAF Plus applications:

Keyboard shortcuts are not required for accessibility. Users should be able to navigate to all parts and functions of the application using the keyboard without using any keyboard shortcuts. Keyboard shortcuts merely provide an additional way to access a function quickly.

C.2 Tab Traversals

Tab traversals allow the user to move focus through different UI elements on a page.

All active elements of the page are accessible by Tab traversal; that is, by using the Tab key to move to the next control and Shift+Tab to move to the previous control. In most cases, when a control has focus, the action can be initiated by pressing Enter.

Some complex components use arrow keys to navigate after the component received focus using the Tab key.

Default Tab traversal order for a page is from left to right and from top to bottom, as shown in Figure C-1. Tab traversal in a two-column form layout does not follow this pattern, but rather follows a columnar pattern. On reaching the bottom, the tab sequence repeats again from the top.

Tab Traversal Sequence

Avoid using custom code to control the tab traversal sequence within a page, as resulting pages would be too difficult to manage and would create an inconsistent user experience across pages in an application and across applications.

To improve keyboard navigation efficiency for users, you should include a skip navigation link at the top of the page, which should navigate directly to the first content-related tab stop.

C.3 Accelerator

Accelerator keys bypass menu and page navigation and perform actions directly. Accelerator keys are sometimes called hot keys. Common accelerator keys in a Windows application, such as Internet Explorer, are Ctrl+O for Open and Ctrl+P for Print.

Accelerator keys are single key presses (for example, Enter and Esc) or key combinations (for example, Ctrl+A) that initiate actions immediately when activated. A key combination consists of a meta key and an execution key. The meta key includes Ctrl (Command on a Macintosh keyboard), Alt (Option on a Macintosh keyboard), and/or Shift. The execution key is the key that is pressed in conjunction with the meta key.

BLAF Plus components have some built-in accelerator keys. Custom accelerator keys are supported only in menus, as shown in Figure C-2.

Accelerator keys has the following guidelines:


In Windows, users have the ability to assign a Ctrl+Alt+character key sequence to an application desktop shortcut. In this case, the key assignment overrides browser-level key assignments. However, this feature is rarely used, so it can generally be ignored.

You must not use the accelerator keys listed in Table C-1 that are already built into page-level BLAF Plus components

Certain BLAF Plus components have built-in accelerator keys that apply when the component has focus. However, if menu commands on the same page have the same accelerator keys, the menu commands take precedence, so the component-level accelerators will not work. Thus, the accelerator keys listed in Table C-2 should be avoided in menus when the related component also appears on the same page.

C.4 Access Keys

Access keys move the focus to a specific UI element.

Access keys relocate cursor or selection focus to specific interface components. Every component on the page with definable focus is accessible by tab traversal (using Tab and Shift+Tab); however, access keys provide quick focus to frequently used components. Access keys must be unique within a page.

The result of pressing access keys depends on the associated element and the browser:

Access keys are triggered with Shift+Alt+mnemonic in Firefox and Alt+mnemonic in Internet Explorer.

If the mnemonic is present in the text of the component label or prompt (for example, a menu name, button label, or text box prompt), it is visible in the interface as an underlined character, as shown in Figure C-3. If the character is not part of the text of the label or prompt, it is not displayed in the interface.

Access keys have the following usage guidelines:


For translation reasons, you should specify access keys as part of the label. For example, to render the label Cancel with the C access key, it is recommended to use &Cancel in the textAndAccessKey property (where the ampersand denotes the mnemonic) rather than C in the accessKey property. Product suites must ensure that access keys are not duplicated within each supported language and do not override access keys within each supported browser unless explicitly intended.

C.5 Default Cursor or Focus Placement

The default cursor puts the initial focus on a component so keyboard users can start interacting with the page without excessive navigation.

Focus refers to a type of selection outline that moves through the page when users press the tab key or access keys. When the focus moves to a field where data can be entered, a cursor appears in the field. If the field already contains data, the data is highlighted. In addition, after using certain controls (such as a list of values (LOV) or date-time picker), the cursor or focus placement moves to specific locations predefined by the component.

During the loading of a standard BLAF Plus page, focus appears on the first focusable component on the page — either an editable widget or a navigation component. If there is no focusable element on the page, focus appears on the browser address field.

Default cursor and focus placement have the following usage guidelines:

C.6 Enter Key

The Enter key triggers an action when the cursor is in certain fields or when focus is on a link or button. You should use the Enter key to activate a common commit button, such as in a Login form or in a dialog.

Many components have built-in actions for the Enter key. Some examples include:
