... We want to clear these up, see if we need to reassign or give
new dates ro what?
Closing action 32 as previously completed.
Closing action 34 as completed.
Updating action 35 to have a date of March 2010.
Closing action 37 as completed because section 1 has been updated.
Updating action 39 to assign to Jim and setting to a due date in
December.
Group talking about action 40 around a technique for a simplified
style sheet for clean printing.
Closing action 40.
<greg> Issue: It might be good for an SC to specifically require UA
to allow the user to use any style sheet, including print-oriented
style sheets, on the screen. That would allow them to take advantage
of simplified layouts created for printing.
<trackbot> Created ISSUE-49 - It might be good for an SC to

Updating issue 41 to a December deadline.
Closing 42, repalced by action 230 which is a more comprehensive
multimedia success criteria on Mark.
Closing action 43 dealing with selecting audio only from video
stream. User agents/content providers may want to consider this as a
feature but not accessibility specific enough.
Discussion around action 44 dealing with scaling of captioned text.
KFord: I think our general let you do what you want with the text
applies here.
Greg: We should be more explicit that we want this to apply to all
text from the author or other sources of text that appear in the
user agent.
Updating action 44 to be explicit.
Updated action 45 with new guideline number and changed the date.
Closing action 46 becuase is covered by other actions.
Issue: When working through our docuemnt we need to be sure that
examples and success criteria reflect our true intnet. Namely, if
text appears in the UA from any source we want the user to have
control over as many of the attributes of that text as possible.

Drqaft for 4.1.9.
Users need to be in control of how they interact with the user
agent. Assistive technology and physical keyboard input needs mean
that certain keyboard combinations are easier for a user to enter.
For example ctrl+f may be a command in a screen reader to read the
itemm with focus and this is also typically a user agent find
command. The user agent needs to allow the user to reassign the...
scribe: find command to a more appropriate key binding. To allow
this level of user control, a user agent may provide a list of user
interface features and default keyboard assignments with options for
the user to assign new key combinations.
<mth> draft 4.1.11 Intent
<mth> Content authors may utilize the Accesskey attribute and ARIA
to define short cut keys which allow quick access to specific parts
of their Web content. The author selected short cuts may utilize
keystrokes that
<mth> are unique to their site, differing from conventions used, and
or familiar, to users of other similar sites, or sites
<mth> offering similar functionality. Users of assistive
technologies who rely upon keyboard input may
<mth> wish to have a consistent mapping of shortcut keys to commonly
accessed parts of a Web site. User agents should allow
<mth> users to define a preferred accesskey for common content
elements, as defined by their ARIA role, and which override
<mth> any author specified keybinding for that page content. The
user should have the option to make any defined override to be
<mth> persistent across browsing sessions.
updated 4.1.9 intent and example.
Users need to be in control of how they interact with the user
agent. Assistive technology and physical keyboard input needs mean
that certain keyboard combinations are easier for a user to enter.
For example ctrl+f may be a command in a screen reader to read the
itemm with focus and this is also typically a user agent find
command. The user agent should allow the user to reassign the...
scribe: find command to a non-conflicting key binding. To allow this
level of user control, the user agent could provide a list of user
interface features and default keyboard assignments with options for
the user to assign new key combinations. User keyboard
customizations should be saved similar to other user preferences by
the user agent.
+4.1.12 draft.
For many users, including those who use the keyboard or and input
method such as speech, the keyboard is often a primary method of
user agent control. It is inportant that direct keyboard commands
assigned to user agent functionality be discoverable as the user is
exploring the user agent. For example, the speech input user who
sees a button on a toolbar needs to be able to determine that...
scribe: ctrl+p is the keyboard equivalent for activating the print
button. If such key assignments are not displayed as the user
interface by default, a user agent should have an option to alter UI
display to include all direct hotkey assignments visually near the
commands such assignments activate.
<jeanne> 4.1.1 Keyboard Operation Intent
<jeanne> A user should be able to navigate, read and use all of the
web page or application without needing to use a mouse. Some users
do not use a mouse, others can only use a pointing device that uses
the keyboard API. Therefore, nsure that the user can interact with
enabled elements, select content, navigate viewports, configure the
user agent, access documentation, install the user agent, and
operate user interface controls, all entirely through keyboard
input.
<jeanne> User agents generally support at least three types of
keyboard operation:
<jeanne> 1. Direct (e.g., keyboard shortcuts such a "F1" to open the
help menu; see checkpoint 11.4 for single-key access requirements),
<jeanne> 2. Sequential (e.g., navigation through cascading menus),
and
<jeanne> 3. Spatial (e.g., when the keyboard is used to move the
pointing device in two-dimensional visual space to manipulate a
bitmap image).
<jeanne> User agents should support direct or sequential keyboard
operation for all functionalities. Furthermore, the user agent
should satisfy this checkpoint by offering a combination of
keyboard-operable user interface controls (e.g., keyboard operable
print menus and settings) and direct keyboard shortcuts (e.g., to
print the current page).
<jallan> comments -example for spatial, should not just be graphics.
for example navigating a table, or moving to the same horizontal
location on vertical lines.
<jeanne> 4.1.1 Keyboard Operation Intent
<jeanne> A user should be able to navigate, read and use all of the
web page or application without needing to use a mouse. Some users
do not use a mouse, others can only use a pointing device that uses
the keyboard API. Therefore, nsure that the user can interact with
enabled elements, select content, navigate viewports, configure the
user agent, access documentation, install the user agent, and
operate user interface controls, all entirely through keyboard

print menus and settings) and direct keyboard shortcuts (e.g., to
print the current page).
<jeanne> 2nd try:
<jeanne> Example:
<jeanne> The user must be able to do the following through the
keyboard alone (or pointing device alone or voice alone):
<jeanne> * Select content and operate on it. For example, if the
user can select rendered text with the mouse and make it the content
of a new link by pushing a button, they also need to be able to do
so through the keyboard and other supported devices. Other
operations include cut, copy, and paste.
<jeanne> * Set the focus on viewports and on enabled elements.
<jeanne> * Install, configure, uninstall, and update the user agent
software.
<jeanne> * Use the graphical user interface menus. Some users may
wish to use the graphical user interface even if they cannot use or
do not wish to use the pointing device.
<jeanne> * Fill out forms.
<jeanne> * Access documentation.
<jeanne> An author uses the CSS overflow property to constrain the
size of a block of content. The user agent provides scroll bars to
display text that overflows the container. The user can use the
keyboard to enter the element and operate the scrollbars to visually
access the content. The user can return to the main flow of the next
element on the page (see SC 4.1.3)
<jeanne> The author codes a volume control slider widget. The user
can focus on the widget, and using the arrow keys to increase or
decrease the volume, and then hit another key to move to the next
element in the content.
<jallan> comments - example - the user places the caret on an
element with a title attribute, the tooltip should be visible and
remain visible while the caret is in the element
<jallan> comment - keyboard user, must navigate to an element to
interact with the element, direct access is more efficient
<jallan> comment - tooltip display should be under the control of
the user. user should be able to turn off tooltip on caret 'focus'
or element focus on active elements
<jallan> comment - on additional resources - or an overview of
guideline 4, write an overview of keyboard accessbility, then get
specific for success criteria

<jeanne> 4.1.2
<jeanne> Intent:
<jeanne> There are many layers of software that can specify what
happens when the user presses a key. For example, the operating
system, the user agent interface, the addons or extensions, and
author supplied accesskeys or javascript. In addition, the assistive
technology the user may be employing will also have assigned key
commands. This results in conflicts in order of operations. These
conflicts impact user expectations of what will happen when a key is
pressed, cau
<jeanne> user expectations of what will happen when a key is
pressed, causing confusion and failure. The most problematic
situation is when the author supplied scripting has precedence on
the keyboard commands. Therefore, the user needs a preference that a
default order: Operating system, user agent interface,
addon/extension, accesskeys, javascript.
<jeanne> comment: Remove :the most problematic"
<jeanne> The author codes a script that makes bananas dance on the
screen when the user presses Alt-F. The user expectation is that
Alt-F will open a file menu. When the bananas dance instead of
opening the file menu, the user is confused or blocked from opening
the file menu and has no recourse. Therefore, the user agent
provides a preference setting that makes the Alt-F open the file
menu. There needs to be a toggle ability, so that the user who wants
to make the banan
<jeanne> the bananas dance can do so.
<jeanne> comment: repetitive list of the order.
<jallan> issue: in 4.1.2 how to make a keystroke cascade, trickle
down from UA interface, extensions, accesskeys, scripts. if ALT F
opens file menu, but the script need the ALT F how UA provide
mechanism to pass the ALF F to the script and not open the menu
<trackbot> Created ISSUE-52 - In 4.1.2 how to make a keystroke

Group returning from lunch. Picking up with review of techniques.
4.1.2
<jallan> comment - direct access for keystroke...go to a menu of
bound keys, then ALT-F will have 3 items in a sub menu - file menu,
accesskey binding, script function
<jallan> or user hits ALT-F dialog pops-up listing bindings, file
menu, accesskey function, scripted function
<jallan> what is still needed is a way for javascript to provide a
list of bound keys to the UA with human friendly names
Twitter list of HTML 5 task force people.
[32]https://twitter.com/laura_carlson/html5accessibilitytf
[32] https://twitter.com/laura_carlson/html5accessibilitytf
<jallan> to support i18n, localizaition, the UA should provide a
mechanism for JS to present binding info - key, name, etc. to the UA
to resolve conflicts
<jallan> is the above a requirement. this would allow the discovery
of keys in use and provide alternative access methods
<jallan> perhaps send to APIWG?
4.1.3
<jeanne> Intent: If the user can put focus on an element, that they
can remove focus and move on to the next element. This is often a
problem with embedded objects. The user agent needs to provide a way
to always return to the previous or next element in the content, or
a known location, such as the address bar. The user agent also needs
to be able to take control back from the embedded object, no matter
what it is.
<jeanne> a) The user can press tab to put focus on an embedded
object and can press shift-tab to move focus to the previous object
and tab to move focus to the next object.
<jeanne> b) the user has moved the focus to a toolbar extension that
does not relinquish control back to the user agent. The user can
press Alt-D to move focus to the address bar.
<jeanne> c) the user has moved the focus to an embedded scripted
application that was poorly programmed. the user can press alt-N (or
any documented key combination) that overrides the scripting and
moves the focus to the next element in the content.
<jallan> comment- what happens if this function is not there. the
user cannot move out of the object/element without restarting
browser or restarting computer
<jallan> issue: need definition of 'browser extension'
<trackbot> Created ISSUE-53 - Need definition of 'browser extension'
; please complete additional details at
[33]http://www.w3.org/WAI/UA/tracker/issues/53/edit .
[33] http://www.w3.org/WAI/UA/tracker/issues/53/edit
<jallan> comment - used to an issue in Flash, could move focus in,
move around but never out again, only solutions was to refresh the
page
4.1.4 separate selection from activation
<jeanne> This is a repair function for when an author violates WCAG,
but the user still needs to be able to read a page without
necessarily activating any controls.
<jeanne> when a user opens a drop down menu from the keyboard, they
must be able to use the arrow keys to move up and down the list,
without triggering an action from the items they are moving past.
<jeanne> A list of radio buttons where putting the focus on the
radio button to read it causes the radio button to be selected. The
user should be able to arrow or tab through the list of radio
buttons without causing any one to be selected. Selection is a
separate discrete operation like spacebar. This overrides any author
provided scripting behavior.
<jallan> comments - intent, not just WCAG, only 1 example violates
wcag
<jallan> another example - form field has data validation, user can
not exit field until user enters valid data.
4.1.5 Present Direct Commands in Rendered Content
<greg> Intent:
<greg> Make it easy to for users to discover or be reminded of
keyboard shortcuts and similar commands without leaving the context
in which they're working. Easy keyboard access is especially
important for people who cannot easily use a mouse.
<greg> Examples:
<greg> "[Ctrl+t]" displayed after a link whose accesskey value is
"t".
<greg> An audio browser reading the value or label of a form control
followed by "accesskey control plus t").
<greg> Mnemonic letters in menu titles are shown with an underline.
<jallan> comment - applicable shortcut indicated or otherwise
highlighted
4.1.6 Standard Text Area Navigation Conventions:
<greg> Intent:
<greg> Providing a full set of keyboard inputs allows users to
efficiently--or at all--perform necessary tasks.
<greg> Making these inputs consistent within and across programs
greatly reduces learning curve, cognitive load, and errors.
<greg> Examples:
<greg> Directional keys, letter keys, and the Enter key function
should allow navigation within and activation of drop-down menus.
<greg> Ctrl+C or Command+C should copy selected text to the
clipboard, allowing the user to avoid manually retyping, and
possibly needing to memorize, large amounts of data.
<jallan> comment - what happens when things are not consistent.
closing dialog boxes are inconsistent ESC or ALT-F4,
<jallan> ...might be text area keyboard conventions/controls, not
just navigation.
<jallan> Ctrl-C is not a navigation command
<jallan> not menus, use select text in content,
<jallan> need to update examples
<jallan> topic 4.1.7 Keyboard Navigation
<jallan> issue: do we have a SC to support OS conventions for cut
copy paste etc
<trackbot> Created ISSUE-54 - Do we have a SC to support OS
conventions for cut copy paste etc ; please complete additional
details at [34]http://www.w3.org/WAI/UA/tracker/issues/54/edit .
[34] http://www.w3.org/WAI/UA/tracker/issues/54/edit
<greg> Intent:
<greg> Let the user navigate between sections without having to
sequentially navigate through everything in every section. Efficient
keyboard navigation is especially important for people who cannot
easily use a mouse.
<greg> Examples:
<greg> Ctrl+Tab moves the focus to the first navigable item in the
next frame.
<greg> The Tab key moves the focus to or away from a group of radio
buttons, and then directional keys move between buttons within that
group.
<jallan> comment - need to be able to choose to go to first item or
to last point of regard in a viewport
<jallan> Kim: no this is Ok
<jallan> GL: need a keystroke to get to first or last active element
on a page. what about moving within a group of radio buttons
<jallan> example - consistency - menu wrapping navigation. ISO
should warn user of wrapping
<jallan> 4.1.7 seems ambiguious, apply only to UI toolbars, menus or
also to content groups of radio buttons
<jallan> issue: 4.1.7 seems ambiguious, apply only to UI toolbars,
menus; or apply also to content - groups of radio buttons
<trackbot> Created ISSUE-55 - 4.1.7 seems ambiguious, apply only to
UI toolbars, menus; or apply also to content - groups of radio
buttons ; please complete additional details at

<jallan> note - fix example of ctrl+tab so it does not proscribe
specific focus location
4.1.8 Important Command Functions
<greg> Intent:
<greg> Let the user access commonly used functions as efficiently as
possible. Efficient keyboard navigation is especially important for
people who cannot easily use a mouse.
<greg> Examples:
<greg> The user can open a document by pressing Ctrl+O or Command+O.
<greg> The user can temporarily enlarge the rendered content by
pressing Ctrl+Plus, rather than having to invoke a menu, choose a
command to display a dialog box, select a tab, etc.
#HTML5 WG #tpac09 Nov 5, breakout sessions irc://irc.w3.org/
#html-wg #html-wg2 #aapi & #video
<jeanne> resources should link to 1.1 Comply with applicable
specifications and conventions
<jallan> comment - seems these are specific instances of why to use
OS conventions (cut/copy/paste, file menu, etc)
<jallan> ...1.1 is so generic. we need to write techniques
4.1.9 Override of UI Keyboard Commands
4.1.9
Intent:
Users need to be in control of how they interact with the user
agent. Assistive technology and physical keyboard input needs mean
that certain keyboard combinations are easier for a user to enter.
Example:
Ctrl+f may be a command in a screen reader to read the itemm with
focus and this is also typically a user agent find command. The user
agent should allow the user to reassign the find command to a
non-conflicting key binding. To allow this level of user control,
the user agent could provide a list of user interface features and
default keyboard assignments with options for the user to...
scribe: assign new key combinations. User keyboard customizations
should be saved similar to other user preferences by the user agent.
<jallan> another example - one handed keyboardist needs to map all
keys to the left side of the keyboard
4.1.11 User Override of Accesskeys
<mth> 4.1.11 Intent
<mth> Content authors may utilize the Accesskey attribute to define
short cut keys which allow quick access to specific elements,
actions, or parts of their Web content. The author selected short
cuts may utilize keystrokes that are unique to their site, differing
from conventions used, and or familiar, to users of other similar
sites, or sites offering similar functionality. Users of assistive
technologies who rely upon keyboard input may wish to have a
<mth> consistent mapping of shortcut keys to similar, or common
actions or functions across the sites they visit.
<mth> User agents should allow users to define a preferred key
combination for specific instances of author defined accesskeys. The
user should have the option to make any defined override to be
persistent across browsing sessions.
<mth> User agents may also offer the user the option to
automatically apply preferred key combinations for content which has
author supplied accesskey bindings, based upon the associated text,
label, or ARIA role, and which override any author specified
keybinding for that page content.
<mth> Example
<mth> A speech recognition user has defined standard commands to
access commonly used parts of a Web site. For example, speaking the
the command "site search" will take the user to a Web site's search
function. A site author may assign an access key to set focus to the
search input field, basing the accesskey on the first letter of the
search engine used (e.g., G for Google or B for Bing, rather than
the mnemonic S for search). The speech user has specified
<mth> an override key mapping of S, which is consistent with the
keystroke issued by the speech recognizer they are using.
<mth> A mobile device user, whose primary keyboard interface is
their phone's numeric keypad, maps common Web site actions to
numeric shortcut keys. For example, the user prefers to have the 1
key to activate a site's "skip to content" function. An author of a
site visited daily by this user defines "S" as the accesskey for the
skip to content function. The user overrides the author defined
accesskey of "S" with "1".
<jallan> comment - good place to add i18n example, accesskey - o
umlaut, but not on local keyboard
<jallan> comment - intent explains how you do it, not why you do it.
<jallan> ...seem to be a technique. where do techniques go.
<jallan> intent - is why, understanding the issue. examples seem to
scenarios with expected behaviors.
<jallan> do we need another section for expanding intent, need more
subheads...intent, examples, how, resources, ???
4.1.10 Specify preferred keystrokes
<jallan> perhaps should be AAA and follow 4.1.11
<jallan> intent: User agents may also offer the user the option to
automatically apply preferred key combinations for content which has
author supplied accesskey bindings, based upon the associated text,
label, or ARIA role, and which override any author specified
keybinding for that page content.
<jallan> comment - not reader friendly, techanleze
<greg> Rewrite of 4.1.10 ("Specify preferred keystrokes") includes
the clause "except for conventional bindings for the operating
environment"; please rewrite to clarify whether this is PROHIBITED
or OPTIONAL.
<greg> The previous also applies to 4.1.9, and possibly others.
4.1.12 Present Direct Commands in User Interface
4.1.12
Intent:
For many users, including those who use the keyboard or and input
method such as speech, the keyboard is often a primary method of
user agent control. It is inportant that direct keyboard commands
assigned to user agent functionality be discoverable as the user is
exploring the user agent.
Example:
The speech input user who sees a button on a toolbar needs to be
able to determine that ctrl+p is the keyboard equivalent for
activating the print button. If such key assignments are not
displayed as part of the user interface by default, a user agent
should have an option to alter UI display to include all direct
hotkey assignments visually as part of the controls the hotkeys
activate.

<jallan> what is difference between 4.1.12 and 4.1.5
<jallan> should be next to each other.
<jallan> why were they separated.
<jallan> 4.1.5 is A, 4.1.12 is AA, web content changes - access keys
can change, UAs generally do not change so revealing keybindings not
as important
<scribe> ACTION: Jeanne to renumber 4.1.12 so it is closer to 4.1.5.
These are the UI and content discovery items for hotkeys. [recorded
in [38]http://www.w3.org/2009/11/05-ua-minutes.html#action01]
<trackbot> Created ACTION-241 - Renumber 4.1.12 so it is closer to
4.1.5. These are the UI and content discovery items for hotkeys. [on
Jeanne Spellman - due 2009-11-12].
<jallan> ...currently no UA meets 4.1.12 Present Direct Commands in
User Interface
<jallan> comment - need to normalize intent across SC
Intent:
Users who rely on accessibility settings do so for multiple reasons
and may want to adjust software settings in many differing fashions.
It is key to allow software settings that impact accessibility to be
configured to meed these differing needs. The easier such settings
are to discover, the more rapidly the user looking for such settings
can tailor the software to suit his or her needs. ...
scribe: Saving such configuration changes between browsing sessions
allows the software to work the way the user wants each time the
application is used.
Example:
A user who relies on larger text sizes when browsing web pages,
locates a text adjustment setting in a browser's menus. The user
sets the text size to the size that makes web contnet readable and
each time the browser is used, the text is adjusted to that user's
settings.
A user locates a control in a web browser called options. Activating
this control leads to a series of tabs for adjusting multiple
browser settings. One tab is listed as accessibility and has
settings such as text size, use custom style sheet, display
alternative text in place of images, enable caret browsing and other
settings determined to be of benefit to users with disabilities.
A user is exploring settings for a web browser and locates an option
called accessibility. The user is then guided through a series of
questions asking about how he or she prefers to use software.
Questions such as color preference, text size, ability to view
images, the need for captions on videos and such are asked. When the
user completes these questions, appropriate browser options...
scribe: are configured and stored.
A user who has configured accessibility settings in a browser needs
to use that application on another computer. The browser allows the
user to transfer such settings from one computer to another, saving
the need to reconfigure the second machine.
4.5 Store preference settings
<jallan> comment - change title to 'configure and store preference
settings'
<jallan> implementing master document:

<jallan> comment - should include what happens if configure and
store is not implemented
<jallan> comment - change font size (control+) is temporary. should
indicate that temporary change should not be persistent.
<jallan> ...user locates the permanant configuration of font size,
sets the size and saves it.
<jallan> " if feature not implemented then user must change the
settings every browser session"
<jallan> new example - user is able to set the default/base font and
font-size for when the author has not defined a font and font size

<jallan> example - user can override author style sheet for font and
font size
4.6.1 Search Rendered Content
<jallan> would be good to label examples with specific success
criteria
<jallan> comment - image with alt HOME, search alt text should be a
preference setting
<jallan> make 2 SC - search text, search alternative
<jallan> or make an option within search (match case, alternative
content, up/down)
<jallan> or provide option to only search alternative content.
<jallan> discussion of Chrome visual indicator on scroll bar of
location of hits. helps show clustering of hits on the page. how
does that get exposed to screen reader etc.
<jallan> it is meta information. not actionable.
4.7.1 Structured Navigation
<greg> Intent:
<greg> Let the user use the keyboard to navigate forwards and
backwards through elements that they are likely to be interested in
interacting with. These elements must include, but are not limited
to, enabled links and controls. This allows the user to jump between
elements without having to navigate through intervening content such
as blocks of text. Efficient keyboard navigation is especially...
<greg> ...important for people who cannot easily use a mouse.
<jallan> comment - important or structural elements are not defined
<greg> Examples:
<greg> The user can press the Tab key to move the focus to the next
link or control in the page, or press Shift+Tab to move in the
reverse order.
<jallan> ...may be many other elements (divs, class), roles, that
user wants to navigate by
<greg> Related Resources:
<greg> See 4.1.4 for discussion of letting the user configure the
list of important elements to suit their task.
<jallan> issue: definition of important or structural elements are
vague, rewrite

elements are vague, rewrite ; please complete additional details at
