NOTE 1: Unless otherwise noted, JFW's "HTML Options" have been left at their default settings. For more information about JFW's "HTML Options", consult the Long Description of JFW 3.5's Default HTML Options Property Sheet, and the accompanying Explanation of JFW 3.5's HTML Options.
NOTE 2: JFW 3.50.25 is the current distribution release of JAWS for Windows. For more information, consult the Henter-Joyce web site, located at: <http://www.hj.com/>
The file named jfw-list-of-links.gif contains a screen shot of Jaws for Window (JFW 3.50.25's "List of Links" feature, which is invoked using the Jaws-specific keystroke INSERT+F7.
The JFW "List of Links" dialog box consists of the following items, listed in tab-order:
In addition, there is a status bar -- reviewable upon demand, using the standard JFW keystroke for bottom-of- window review, INSERT+PageDown -- which exposes the HREF value defined for the chosen link.
(NOTE: Setting MSIE 5.01 to "Show Friendly URLs" does not change the display of the URL in the "List of Links" status bar.).
Each above-listed item is addressable via a HotKey.
By default, links are sorted by tabbing order. The user can quickly change the sorting criterion to alphabetic, either by tabbing to the radio button labeled "Alphabetically" (which is one of the radio buttons grouped under the "Sort Links" legend, which is echoed by JFW as a single string, "Sort Links Alphabetically", when the radio button receives focus) or by using the ALT+P hotkey.
There are also three "Display" options available to the user:
"Display All Links" is the default setting.
As with the "Sort Links" grouping, one can either tab to the "Display" grouping of radio buttons in order to change this value by selecting one of the 3 radio buttons, or one can use the hotkeys associated with each option (ALT+L, ALT+V, and ALT+U, respectively).
NOTE 1: By default, JFW speaks -- and, therefore, lists -- hyperlinks using the TITLE or ALT text defined for the link, if one is present. If no TITLE has been defined for the link, then the hyperlink text (i.e. the text contained between the <A HREF=""> and the </A>) is spoken. In the case of graphically defined hyperlinks, hyperlink text takes precedence over the ALT text defined for the IMG. Currently, this behavior can be modified only by changing the "Text Link Verbosity" setting in the "HTML Options" property sheet of the default JFW configuration file. Thus, one cannot dynamically change the level of "Text Link Verbosity" used in JFW "Links List" on-the-fly. For more information, consult the Long Description of JFW 3.5's Default HTML Options Property Sheet, and the Explanation of JFW 3.5's HTML Options.
NOTE 2: The 3.50.25 build of JFW offers three levels of "Text Link Verbosity":
The "HTML Options" property sheet for the default JFW configuration file also allows one to tailor the announcement of graphics, as well as graphical links, on web pages. Neither the "text Link Verbosity" nor the "Graphic Link Verbosity" settings can be dynamically toggled in any mode. For more information, consult the Long Description of JFW 3.5's Default HTML Options Property Sheet, and the accompanying Explanation of JFW 3.5's HTML Options
NOTE 3: As one moves through the list of links, JFW identifies links using the TITLE or, if no TITLE is present, the hyperlink text defined for the link. The JFW "List of Links" does not discriminate between graphical and non-graphical hyperlinks, save that it will announce the ALT text defined for the image over any hyperlink text that may be included as part of the anchor. However, if the link associated with the graphic has a TITLE, the TITLE defined for the hyperlink takes precedence over the ALT text defined for the graphic.
NOTE 4: The 3.50.25 build of JFW does not announce any information about the status of and/or type of link as one moves through the list. This is in marked contrast to JFW's default action when using JFW's "Virtual PC Cursor" to either navigate blocks of text or when using JFW's "SpeakAll" command. Thus, using the JFW "List of Links", one cannot obtain the extended link type information available when one is reviewing content using the Virtual PC Cursor, which communicates with MSIE using Microsoft Active Accessibility (MSAA).
The supplemental information about links provided by JFW includes:
Sub-Note 4.1: "SpeakAll" is JFW's default action when MSIE 5.01 completely loads a document--please consult the section entitled "A Brief Overview of The User's Experience of Documents Rendered by MSIE 5x When Using JFW 3.5's Virtual PC Cursor" for more information on how the user experiences pages rendered by MSIE 5x when read using JFW 3.5
Sub-Note 4.2: For more information about the type of pseudo-elemental information provided by JFW 3.5 when using the Virtual PC Cursor, consult the section entitled Long Description of JFW 3.5's Default HTML Options Property Sheet, and the accompanying Explanation of JFW 3.5's HTML Options
Hyperlinks are presented in a list box. When the list of links is invoked via the INSERT+F7 keystroke, focus is established in the list box. If the "List of Links" feature is invoked when a page is loaded (i.e. before the user has established focus), the first listed link is highlit.
One can discern the relative position of the link in the list of links using JFW's "Say Window Prompt and Text" command (INSERT+TAB), which causes JAWS to announce:
This orientational mechanism can assist the user, as the first piece of information JFW announces about a page is the number of links it contains. ("Page Has Y Links")
If one invokes the "List of Links" feature after interrupting speech or after manually moving through the page using the Virtual PC cursor, the system cursor is placed on the link which either enjoys the Virtual PC cursor's current point-of-regard or the nearest link to the Virtual PC cursor's point-of-regard. For example, if one used the Virtual PC cursor to move to the following sentence, in which the hyperlink text is displayed in blue underlined text, so as to simulate the visual rendering of the hyperlink by a grapical user agent,
Ais also available.
one would hear:
A this page link list presentation of this table is also available.
Pressing INSERT+F7 would spawn the JFW "List of Links", with the "list presentation of this table" link highlit. Similarly, if one were simply listening to the page using JFW's "SpeakAll" feature, heard the sentence cited above, stopped speech, and then pressed the INSERT+F7 key combination, the list item
list presentation of this table
would be the item-with-focus when the "List of Links" is spawned.
(Note: By default, when a page finishes loading, JFW announces the total number of links in the document, and then begins to "SpeakAll". Speech can be squelched by depressing the CONTROL key.)
Choosing "Move to Link" causes the Virtual PC Cursor to be moved to the chosen link, without activating the link. By default, in build 3.50.25, JFW tracks the Virtual PC Cursor with MSIE's system caret.
