Complete new 2.3.5

2.3.5 Customize Keyboard Commands: The user can override any keyboard
shortcut including recognized author supplied shortcuts (e.g.
accesskeys) and user interface controls, except for conventional
bindings for the operating environment (e.g. arrow keys for navigating
within menus). The user must be able to save these settings beyond the
current session. (Level AA)

Intent of Success Criterion 2.3.5

Some users may be able to hit certain keys on the keyboard with
greater ease than others. Assistive technology software typically has
extensive keyboard commands as well. The goal of this SC is to enable
the user to be in control of what happens when a given key is pressed
and use the keyboard commands that meet his or her needs, and the
ability to save the modifications.@@added from 214@@

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 consistent mapping of
shortcut keys to similar, or common actions or functions across the
sites they visit.

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.

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.

Examples of Success Criterion 2.3.5:

o	A speech recognition user has defined standard commands to access
commonly used parts of a Web site. For example, speaking 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 an override key mapping of S,
which is consistent with the keystroke issued by the speech recognizer
they are using.
o	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".
o	Laura types with one hand and finds keys on the left side of the
keyboard easier to press. She browses to a web page and notices that
the author has assigned access keys using keys from the right side of
the keyboard. She opens a dialog in the user agent and reassigns the
access keys from the web page to the left side of the keyboard home
row. @@added from 214@@
o	Elaine's screen magnification program uses alt+m to increase the
size of the magnified area of the screen. She notices that in her web
browser, alt+m is a hotkey for activating a home button that stops her
from being able to control her magnification software. She opens a
hotkey reassignment feature in the user agent, and sets alt+o to be
the new hotkey for the home button. Her screen magnification software
now works correctly.@@added from 214@@
o	@@ Editors' Note: good place to add i18n example, accesskey - o
umlaut, but not on local keyboard@@


Since 2.1.4 is deleted the summary  for GL 2.1 needs to be rewritten
and GL 2.1 will need to be RENUMBERED.

Summary: Users can operate all functions (2.1.1), and move focus
(2.1.2, 2.1.3) using just the keyboard. Users can activate important
or common features with shortcut keys, (2.1.8),  escape keyboard traps
(2.1.5), specify that selecting an item in a dropdown list or menues
not activate that item or move to that new web page (2.1.6) and use
standard keys for that platform (2.1.7). @@removed section on 214@@
