Table 2. Section 1194,21 Software applications and operating systems - Detail
Criterion Level of support Remarks and explanations
(a) When software is designed to run on a system that has a keyboard, product functions shall be executable from a keyboard where the function itself or the result of performing a function can be discerned textually.

Supported with exceptions

Users cannot select certain interface elements or perform certain functions with the keyboard. [169966, 179530, 187526, 188832, 188833, 188836, 188838]

Pressing ENTER has different effects depending on the table row selected. [188836]

Incorrect default action is specified for certain keystrokes. [188840]

Some controls appear only as images with no text alternative available on the screen. [178076]

Pressing ESC does not close the dialog box (3rd party). [212283]

Pressing ESC does not trigger Cancel button (3rd party). [214696]

Pressing ESC does not close dialog box. [214825]

The URL of a newly created site cannot be copied or pasted (with mouse or keyboard). The workaround for a XenApp Web Site is to launch the “Preview site” task and copy the URL in the browser address bar. [212297]

There is no text equivalent for "rename site." [212304]

You cannot rename a site with the keyboard. [212304]

In the AppCenter, when focus is on the Policies node, access keys in the middle pane are not visible or usable until focus is on a control within the pane. [225558, 225560]

You can use an arrow key to move focus to a radio button, but the radio button is not selected. Press the spacebar to select it (third-party issue). [223355]

You cannot use the keyboard to select text in a read-only text box. [225230]

Some controls are missing labels. [243643, 224986]

Pressing F1 does not open Help in Connection Center. [258686]

In the AppCenter Policies pane, the "Save as Template" menu item sometimes cannot be activated from the keyboard. [259453]

In the AppCenter Policy Templates windows, you cannot use spacebar or Enter to select an item from certain menus. [259451, 260688]

In Desktop Viewer, the list presented after choosing "Devices" cannot always be closed by pressing ESC. [256786]

By design, Desktop Viewer disables most keyboard shortcuts. For more information about shortcuts used when viewing a published desktop, both with and without Desktop Viewer running, please see the section "Keyboard Input in XenDesktop Sessions" in the document Receiver for Windows 3,0. [256770]

(b) Applications shall not disrupt or disable activated features of other products that are identified as accessibility features, where those features are developed and documented according to industry standards. Applications also shall not disrupt or disable activated features of any operating system that are identified as accessibility features where the application programming interface for those accessibility features has been documented by the manufacturer of the operating system and is available to the product developer.

Some text boxes are not clearly visible when you set the display to high contrast (third party). [252619]

(c) A well-defined on-screen indication of the current focus shall be provided that moves among interactive interface elements as the input focus changes. The focus shall be programmatically exposed so that Assistive Technology can track focus and focus changes.

Supported with exceptions

The product was tested with Assistive Technology and can be used with such technology subject to the exceptions in the next column.

Focus is lost after using an arrow key or TAB. [174303]

When navigating around the user interface using the keyboard, focus can move to unexpected elements. [179530, 187528, 188833, 182946]

No interface element is in focus when certain dialog boxes are opened. [188818]

Items do not change color when selected in the Form Definition wizard. [182806, 182815]

You cannot use arrow keys to move focus between buttons in a list (3rd party). [214419]

Focus cannot be put on a read-only control. [224933, 225230]

Focus disappears as you tab around the window. [223215, 225907, 247760, 247772, 252451, 252823, 999999]

If a child window closes, focus disappears. [223215, 259695]

If a child window closes, focus returns to a control other than the one used to open it. [223215, 252452, 259553]

15 seconds after a dialog opens, its parent window, Manage Passwords, steals focus from it. [259559]

The Receiver login window steals focus from child window after 20 seconds, but stays in background, so you cannot see the field that has focus. [259944]

In "Manage Passwords," the Logon Chooser opens so you can choose the correct set of credentials to pass to the application that was just opened. However, focus goes to the application instead of to Logon Chooser. [259562]

In the middle pane of the Delivery Services Console, the standard CTRL+TAB operation does not move focus between tabs. Use left and right arrow keys. [225759]

TAB and arrow keys sometimes move focus to unexpected controls. [225215, 225769]

When viewing the License Administration Console with Internet Explorer 7-9, focus is not visible for links and buttons. In order to make focus visible, use Compatibility View in IE. [225915]

All controls are in the TAB order, but the TAB order is incorrect. [224871, 262209, 262590, 263405]

SHIFT+TAB order is not the inverse of tab order, so focus lands on an unexpected control. [262553]

The TAB key moves focus within a list in the left pane instead of to the list item's corresponding settings in the right pane. To move focus to the right pane, use the right arrow instead. [252723]

In Desktop Viewer Preferences, if you use access key to select a menu item, the focus rectangle does not move to the selected menu item because menu items have been implemented as buttons. [261671]

In Web Interface, the HDX icon is sometimes hidden, but it remains in the tab order. Visual focus disappears when users tab to the HDX icon, but JAWS still detects it. [999999]

(d) Sufficient information about a user interface element including the identity, operation and state of the element shall be available to Assistive Technology. When an image represents a program element, the information conveyed by the image must also be available in text.

The screen reader does not call out the assistive text that appears beneath a button (third party). [243635]

When focus lands on a control, the screen reader only calls out the control type (such as “button,” "link," or "checkbox"), but not the control label. [225918, 263178, 263188, 263334]

When a new window opens, the screen reader does not identify the window title. [231208, 243639]

When a window opens, the screen reader only identifies the window title. [243643]

When the user enters a command to read the entire contents of window, the screen reader only identifies two graphics. [243640, 243641]
