Keyboard Shortcuts

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

Following are the topics covered in this section:

About Keyboard Shortcuts

Keyboard shortcuts are helpful to users as they act as an alternative to mouse. Using keyboard shortcuts for ADF Faces applications can greatly increase your productivity, reduce repetitive strain, and help keep you focused.

Keyboard shortcuts provide an alternative to pointing devices for navigating the page. There are five types of keyboard shortcuts that can be provided in ADF Faces applications:

Tab traversal, using Tab and Shift+Tab keys: Moves the focus through UI elements on a screen.
Accelerator keys (hot keys): bypasses menu and page navigation, and performs an action directly, for example, Ctrl+C for Copy.
Access keys: Moves the focus to a specific UI element, for example, Alt+F for the File menu.
Default cursor/focus placement: Puts the initial focus on a component so that keyboard users can start interacting with the page without excessive navigation.
Enter key: Triggers an action when the cursor is in certain fields or when the focus is on a link or button.

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

It is the application developer’s responsibility to provide user assistance that identifies the application’s available keyboard shortcuts. If the application includes an ADF component that provides keyboard shortcuts, the developer should also provide a popup or other help that details the keyboard shortcuts available for the ADF component.

Tab Traversal

Tab Traversal can be defined as an order in which the elements of the ADF Faces user interface receive keyboard focus on successive passes of the Tab key.

Tab traversal allows the user to move the 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 then be initiated by pressing Enter.

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

Tab Traversal Sequence on a Page

Default Tab traversal order for a page is from left to right and from top to bottom, as shown in Figure 1-1. 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.

Figure 1-1 Tab Traversal Sequence on a Page

Description of "Figure 1-1 Tab Traversal Sequence on a Page"

Avoid using custom code to control the tab traversal sequence within a page, as the 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 set the initialFocusId attribute on the document. For accessibility purposes, you should also define a skipLinkTarget and include a skip navigation link at the top of the page, which should navigate directly to the first content-related tab stop.

Tab Traversal Sequence in a Table

The Tab traversals in a table establishes a unique row-wise navigation pattern when the user presses the Tab key to navigate sequentially from one cell to another. One of the following actions can occur when user presses the Enter key in a table cell:

Clicks on an editable cell and presses Enter key—the focus moves to the editable cell below in the same column in the next row
Clicks on an editable cell, edits the contents of the cell, and presses Enter key—the focus completes the action in the current cell and moves to the editable cell below in the same column in the next row
Clicks on an editable cell and presses Tab key without editing the cell, once or more than once, and then presses Enter key— the focus moves to the editable cell below in the next row, in the same column where the user started pressing the tab key.
Clicks on an editable cell, edits the contents of the cell, and presses Tab key, once or more than once, then presses Enter key—the focus completes the action in the current cell where the user started pressing the Tab key. Focus traverses through the cells sequentially per the number of times the Tab key is pressed. Then, the focus moves to the editable cell below in the next row, in the same column where the user started pressing the tab key
Clicks on a non-editable cell and presses Enter key—the focus moves to the first editable cell in the next row.
Clicks on a non-editable cell and presses Tab key, once or more than once, then presses Enter key—the focus traverses through the cells sequentially per the number of times the Tab key is pressed and moves to the first editable cell in the next row.
Clicks on a cell that contains any command, such as menu, link, or a dialog box, then presses Enter key—the default action for that command is executed

Note:

When user uses the Tab key to traverse through the cells sequentially and presses Enter key to move to the next row , a navigation pattern is formed based on the first set of Tab keys, which is followed in subsequent rows. The navigational pattern is not recognized if arrow keys are used to navigate from one cell to another.

Figure 1-2 shows an example of a Tab and Enter keys traversal sequence in a table.

Figure 1-2 Tab and Enter Keys Traversal Sequence in a Table

This image is described in the surrounding text

In Figure 1-2, the user has navigated the rows without editing any cell in the following way:

The user clicks a cell in the inputText column, giving it focus and making it editable.

Because the Tab key is used to navigate, the inputText column is recognized as the starting column for the navigation pattern.
The user presses the Tab key and moves the focus in the same row to the cell of the * Required field column.
The user presses the Tab key and moves the focus in the same row to the cell of the inputComboListOf column.
The user presses the Enter key and the focus shifts to the inputText column in the next row.

Shortcut Keys

While it is possible to use the tab key to move from one control to the next in an ADF Faces application, keyboard shortcuts like the accelerator and access keys are more convenient and efficient. They help users to navigate around the web application easily and access a menu or function quickly.

There are various keyboard shortcuts provided by ADF Faces itself, as well as component attributes that enable you to create specific keyboard shortcuts for your specific applications. ADF Faces categorizes shortcut keys for components into two types, accelerator keys and access keys.

Note:

It is the application developer’s responsibility to provide user assistance to identify the application’s available keyboard shortcuts. Because an ADF component’s terminology can conflict with an application’s terminology, the application should also provide a popup or other help that details the keyboard shortcuts available for that component.

Accelerator Keys

Accelerator keys bypass menu and page navigation and perform actions directly. Accelerator keys are sometimes also 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 may be Ctrl (Command on a Macintosh keyboard), Alt (Option on a Macintosh keyboard), or Shift. The execution key is the key that is pressed in conjunction with the meta key.

Some ADF Faces components have their own built-in accelerator keys. For example, Ctrl+Alt+M is the accelerator key to open the context menu. For more information about ADF Faces components with their own built-in accelerator keys, see the component tag documentation.

ADF Faces also enable you to provide custom accelerator keys to specific menu items, as shown in Figure 1-3. All assigned menu accelerator keys are visible when you open the menu.

Figure 1-3 Accelerator Keys in a Menu

Description of "Figure 1-3 Accelerator Keys in a Menu"

When defining accelerator keys, you must follow these guidelines:

Because accelerator keys perform actions directly, if a user presses an accelerator key unintentionally, data may be lost or incorrect data may be entered. To reduce the likelihood of user error, accelerator keys should be used sparingly, and only for frequently and repetitively used functions across applications. As a general rule, less than 25% of available functions should have accelerator keys.
Custom accelerator keys must not override accelerator keys that are used in the menus of ADF Faces-supported browsers (see the browser and system requirements for supported operating systems and browsers in ADF Faces), and must not override accelerator keys that are used in assistive technologies such as screen readers.
Custom menu accelerator keys must always be key combinations. The meta key may be Ctrl, Ctrl+Shift, or Ctrl+Alt. Ctrl+Alt is the most used metakey because Ctrl and Ctrl+Shift are commonly used by browsers. The execution key must be a printable character (ASCII code range 33-126).
Custom menu accelerator keys must be unique. If a page were to have different components that used the same accelerator, it would be difficult for the browser to predict which actions would be executed by the accelerator at any given time.

Note:

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.

Certain ADF Faces components have built-in accelerator keys that apply when the component has focus. Of these, some are reserved for page-level components, whereas others may be assigned to menus when the component is not used on a page. Table 1-3 lists the accelerator keys that are already built into page-level ADF Faces components. You must not use these accelerator keys at all.

Table 1-3 Accelerator Keys Reserved for Page-Level Components

Accelerator Key	Used In	Function
Ctrl+Alt+W Ctrl+Shift+W	Pop-up Messaging Secondary Windows	Toggle focus between open popups.
Ctrl+Alt+P	Splitter	Give focus to splitter bar.

The menu commands take precedence if they are on the same page as page-level components, and have the same accelerator keys. For this reason, you must not use the accelerator keys listed in Table 1-5 and Table 1-9 in menus when the related component also appears on the same page.

Access Keys

Access keys move the focus to a specific UI element, and is defined by the accessKey property of the ADF Faces component.

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 triggering an access key depends on the associated element and the browser:

Buttons: In both Firefox and Internet Explorer, access keys give focus to the component and directly execute the action. Note that in Internet Explorer 7 access key gives focus to the component, but does not execute the action.
Links: In Firefox, access keys give focus to the component and directly navigate the link; in Internet Explorer, access keys give focus only to the link.
Other Elements: In both browsers, access keys give focus only to the element. For checkbox components, the access key toggles the checkbox selection. For option buttons, the access key performs selection of the option button.

Note that the access key could be different for different browsers on different operating systems. You must refer to your browser's documentation for information about access keys and their behavior. Table 1-4 lists access key combinations for button and anchor components in some common browsers.

Table 1-4 Access Key For Various Browsers

Browser	Operating System	Key Combination	Action
Google Chrome	Linux	Alt + mnemonic	Click
Google Chrome	Mac OS X	Control + Option + mnemonic	Click
Google Chrome	Windows	Alt +mnemonic	Click
Mozilla Firefox	Linux	Alt + Shift + mnemonic	Click
Mozilla Firefox	Mac OS X	Control + mnemonic	Click
Mozilla Firefox	Windows	Alt + Shift + mnemonic	Click
Microsoft Internet Explorer 7	Windows	Alt + mnemonic	Set focus
Microsoft Internet Explorer 8	Windows	Alt + mnemonic	Click or set focus
Apple Safari	Windows	Alt + mnemonic	Click
Apple Safari	Mac OS X	Control + Option + mnemonic	Click

Note:

Different versions of a browser might behave differently for the same access key. For example, using Alt + mnemonic for a button component in Internet Explorer 7 sets focus on the component, but it triggers the click action in Internet Explorer 8.
In Firefox, to change the default behavior of the component when access key combination is used, change the configuration setting for the accessibility.accesskeycausesactivation user preference.
Some ADF Faces components that are named as Button do not use HTML button elements. For example, af:button uses an anchor HTML element.

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 1-4. If the character is not part of the text of the label or prompt, it is not displayed in the interface.

Figure 1-4 Access Key

When defining access keys, you must follow these guidelines:

Access keys may be provided for buttons and other components with a high frequency of use. You may provide standard cross-application key assignments for common actions, such as Save and Cancel. Each of these buttons is assigned a standard mnemonic letter in each language, such as S for Save or C for Cancel.
A single letter or symbol can be assigned only to a single instance of an action on a page. If a page had more than one instance of a button with the same mnemonic, users would have no way of knowing which button the access key would invoke.
Focus change initiated through access keys must have alternative interactions, such as direct manipulation with the mouse (for example, clicking a button).
The mnemonic must be an alphanumeric character — not a punctuation mark or symbol — and it must always be case-insensitive. Letters are preferred over numbers for mnemonics.
In Internet Explorer, application access keys override any browser-specific menu access keys (such as Alt+F for the File menu), and this can be a usability issue for users who habitually use browser access keys. Thus, you must not use access keys that conflict with the top-level menu access keys in ADF Faces-supported browsers (for example, Alt+F, E, V, A, T, or H in the English version of Internet Explorer for Windows XP).
You are responsible for assigning access keys to specific components. When choosing a letter for the access key, there are a few important considerations:
- Ease of learning: Although the underlined letter in the label clearly indicates to the user which letter is the access key, you should still pick a letter that is easy for users to remember even without scanning the label. For example, the first letter of the label, like Y in Yes, or a letter that has a strong sound when the label is read aloud, such as x in Next.
- Consistency: It is good practice to use the same access key for the same command on multiple pages. However, this may not always be possible if the same command label appears multiple times on a page, or if another, more frequently used command on the page uses the same access key.
- Translation: When a label is translated, the same letter that is used for the access key in English might not be present in the translation. Developers should work with their localization department to ensure that alternative access keys are present in component labels after translation. For example, in English, the button Next may be assigned the mnemonic letter x, but that letter does not appear when the label is translated to Suivantes in French. Depending on the pool of available letters, an alternative letter, such as S or v (or any other unassigned letter in the term Suivantes), should be assigned to the translated term.

Note:

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, you should 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.

Default Cursor or Focus Placement

When a user opens an input form (built with ADF Faces) to enter some data, the default cursor is placed on the most suitable component so that the user can proceed with the help of a keyboard instead of using a mouse first. After the initial focus is set, the user can take control on cursor position.

The default cursor puts the initial focus on a component so that 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 ADF Faces 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.

When defining default cursor and focus placement, you should follow these guidelines:

ADF Faces applications should provide default cursor or focus placement on most pages so that keyboard users have direct access to content areas, rather than having to tab through UI elements at the top of the page.
You can set focus on a different component than the default when the page is loaded. If your page has a common starting point for data entry, you may change default focus or cursor location so that users can start entering data without excessive keyboard or mouse navigation. Otherwise, do not do this because it makes it more difficult for keyboard users (particularly screen reader users) to orient themselves after the page is loaded.

The Enter Key

The Enter key in an ADF Faces application causes a command line, form, or dialog box to operate its default function. It is typically used to finish an input form and begin the desired process.

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:

When focus is on a link or button, the Enter key navigates the link or triggers the action.
When the cursor is in a query search region, quick query search, or Query-By-Example (QBE) field, the Enter key triggers the search.
When in a table, pressing the Enter key triggers one of the following actions:
- Clicks on an editable cell and presses Enter key—the focus moves to the editable cell below in the same column in the next row
- Clicks on an editable cell, edits the contents of the cell, and presses Enter key—the focus completes the action in the current cell and moves to the editable cell below in the same column in the next row
- Clicks on an editable cell and presses Tab key without editing the cell, once or more than once, and then presses Enter key— the focus moves to the editable cell below in the next row, in the same column where the user started pressing the tab key.
- Clicks on an editable cell, edits the contents of the cell, and presses Tab key, once or more than once, then presses Enter key—the focus completes the action in the current cell where the user started pressing the Tab key. Focus traverses through the cells sequentially per the number of times the Tab key is pressed. Then, the focus moves to the editable cell below in the next row, in the same column where the user started pressing the tab key
- Clicks on a non-editable cell and presses Enter key—the focus moves to the first editable cell in the next row.
- Clicks on a non-editable cell and presses Tab key, once or more than once, then presses Enter key—the focus traverses through the cells sequentially per the number of times the Tab key is pressed and moves to the first editable cell in the next row.
- Clicks on a cell that contains any command, such as menu, link, or a dialog box, then presses Enter key—the default action for that command is executed
Note:
When user uses the Tab key to traverse through the cells sequentially and presses Enter key to move to the next row , a navigation pattern is formed based on the first set of Tab keys, which is followed in subsequent rows. The navigational pattern is not recognized if arrow keys are used to navigate from one cell to another.
