Adobe has recently released updates to their Creativity Suite 4 (CS4) line of 
products, which include Dreamweaver, Photoshop, Flash, and more.  They claim to 
have accessibility improvements in many of these products,but the Flash 
improvements stood out to me as the most significant!  I immediately thought 
this is great, but it will take years before I notice any improvements in 
popular sites.  To my astonishment, I viewed a video on YouTube.com and the 
interface is already very accessible and implements these features!  Hopefully, 
other sites update their websites quickly!  I have yet to understand how the 
volume and seek slider controls are moved with the arrow, Home and End keys 
with JAWS as described.  I tried to force JAWS to be in Forms Mode in both 
versions 9 and 10 beta, to enable the arrow, Home, and End keys to affect the 
control, but I am not sure how to do this.  Maybe, I could try to use the JAWS 
pass-through keystroke (Insert 3), but that would be cumbersome since you would 
probably want to use multiple, repeated use of an arrow key on one of these 
sliders.  Any ideas? 

Below is a short description of the enhancements from Adobe's site:


Adobe Flash accessibility design guidelines 
Accessible video controls 
Adobe® Flash® CS4 Professional software provides industry-leading support for 
accessible video. Providing captions for video solves accessibility challenges 
for people who are deaf or hard-of-hearing, but people who are blind or who 
have low vision or other physical disabilities need the video playback controls 
to be keyboard accessible and to function properly with assistive technologies 
such as screen readers and screen magnifiers. Flash CS4 Professional offers 
improvements to the FLVPlayback video component that make the default player 
controls accessible automatically, without any coding required by the 
developer. 

Simple implementation 
All skins provided by Flash CS4 Professional support keyboard and screen reader 
access, so developers simply insert the FLVPlayback component on the stage in 
Flash - no configuration is needed. 

Accessible interaction 
Users who rely on keyboard access can utilize a variety of familiar shortcuts 
to interact with the video controls. Buttons such as Play/Pause, Stop, Rewind, 
Mute, and Closed Captions can be tabbed to and activated with the spacebar key. 
Slider controls such as the volume and playhead position controls can be 
accessed via the arrow keys, and the Home and End keys can be used to go 
directly to the beginning or end of the range. The volume slider also accepts 
numeric keys to set the playback audio levels in one quick step.

Users who use screen readers will find appropriate names for the video player 
controls that ensure that each control's purpose is clear. Some controls 
require that the screen reader is in form interaction mode (which is Forms mode 
in JAWS or Browse Off mode in Window-Eyes) because screen readers often utilize 
arrow keys and other shortcuts for other purposes. For example, many screen 
readers use right and left arrow keys to read individual letters in text and 
control labels, so these keys are not available outside of form interaction 
mode, as expected by users.
