Browser User Interface Accessibility Check List
1=highest, 2=middle, 3 lowest priority, ADD=Item to add, ?=I do not have
enough information or understanding to make a recommendation, JA:=my comments 

Presentation Adjustability
JA: I am not sure of the distinction between disable and Override. For
example, in IE or Navigator when a user says use "my colors" is that
overriding the authors colors or disabling the authors colors. Or does
Override include disable?
 
? Author CSS disable 
? Author color disable 
? Author font disable 
? Author background disable 
1 User CCS override 
1 User foreground/background color override 
1 User font style and size override 
1 Display only ALT text for images (complete ALT text) 
1 Display TITLES for anchors that are images 
ADD Display ALT text and Titles for anchors that are images
ADD Display text within OBJECT tag
1 Display LONGDESC discriptions on user command 
3 Display view option for headers only 
3 Display view option for headers and anchors only 
1 Display view option based on users preferences of selected elements 
1 Maintain relative focus positions between views 
? Suspend Dynamic HTML events 

Orientation Information
1 Document TITLE in title line 
2 Document summary information on status line on document load 
1 Document summary information on status line on user command 
1 Selected document summary information in menu items (see visibility
section) 

JA: this should also be included in Navigation section

2 Element identification on status line on focus/mouse over (see next
section for psuedo focus) 

Navigation Commands
Text highlight, an insert cursor or other indicator usable by assistive
technology is needed as a psuedo focus for 3rd party assistive technology
for navigation of HTML elements.  The psuedo focus is needed for most of
the following navigation commnands to benefit users with disabilities. 
The following is an initial list of navigation commands.  The commands
should be available from the keyboard, menus and possibly in a user defined
set of toolbar commands. 

List of Important Navigation Commands

Link (Anchor)
1 Move to previous link
1 Move to next link
1 Move to link from list 
ADD Move to link from menu
ADD Move to link from command line (see Scott L. message about Lynx and links)
1 Select link

Headers
1 Move to previous header
1 Move to next header
1 Move to header from list
ADD Move to header from menu 

List Items
1 Move to previous list item
1 Move to next list item
? Move to list item from list JA: what is the purpose of this

Forms

engines

Visibility of Accessibility Information
1 Display keyboard equivalents on associated menu items 
1 Display navigation commands in menus 
(For example have a main menu item labled nn Headers, where nn is the
number of headers in
the current document. The sub menu items would include Next Header,
Previous Header, List of
All Headers, and a Dynamic List of the first 10 headers.) 
1 Discription of navigation command and selection options in on-line
documentation 
1 Discription of presentation options in on-line documentation 
1 Discription of orientation information options in on-line documentation 

? Compatibility with 3rd Party Assistive Technology 
JA: I am not sure how this would work. There are many 3rd party assitive
tech addon. Would each browser be required to test with all tools
available? Or, should browser manufactures publish or codevelop or use some
other mechanism to ensure that 3rd party developers have a standard way to
access the information. 

? Use Active Accessibility in Windows 95/NT Code 

? Use SUNSoft Java Accessibility API in Java Code 
1 Use of Standard OS Controls/Menus/Dialog boxes
