Ginny was asking about whether hot spots can be used to mark locations that VoiceOver can't get to. I assume this is really for apps with accessibility issues rather than web pages like the Audible.com site example I gave. Hot spots only work to store temporary information on the state of the system for the configuration you're working with. Since VoiceOver can't store information about where these elements are, I assume that the reason Ginny wasn't able to use hot spots that saved cursor locations where a sighted friend had moved a cursor to get to these places was that as soon as she started using VoiceOver, it had no way to recognize these positions. It's possible that these positions might be remembered if Mouse Keys were turned on and a hot spot were created, but she'd have to go back to using Mouse Keys to navigate so she could return to the hot spot. Mouse Keys are typically used as an accessibility solution for sighted users who don't have fine motor control of a Mouse, maybe because of a physical disability like Parkinson's disease, so they use the arrow keys on the numeric keypad to move the mouse cursor up, down, left, or right by pressing the direction keys a fixed number of times. VoiceOver does provide a way to read off the pixel coordinates of your cursor as you move it (VO-F5 twice). But, just as you can only move your cursor to points that VoiceOver recognizes when you use VoiceOver to navigate apps and web pages, when you have Mouse Keys turned on, you can only move your mouse cursor by navigating with key presses, so I turn cursor tracking off. If you don't have a track pad to use for clicking (to start Audio samples playing on the Audible.com site), then you can press the button on a connected mouse, or you can turn on NumPad Commander and press the "5" key on a numeric keypad, and I'm sure there are other ways to "click" with assignments in Snow Leopard. The actual pixel locations of the flash players on the Audible.com web page change depending on what content is loaded, but until they redesign the web page layout, the offsets from the reference point do not -- I just move to "Sample" for the audiobook and then use mouse keys to move my cursor 50 pixels to the right so I can click on the flash player. I mentioned that this is the current spacing they use when you run a "search" and retrieve one or more matches. On the individual audiobook web pages the pixel offset is larger. This works for the settings on my MacBook -- you might have to calibrate the offset number of pixels to use on another computer. Note that this web page design has worked for several months, but it is a different design from the one that Josh reported on at the Mac-cessibility web page a year ago -- you can't use those instructions any more. HTH. Note that most of the discussion in this post has shifted from hot spots to using mouse keys. And for obvious reasons, it won't help to set a hot spot for the Audible web site in Safari -- unless you never intend to use your browser for any other site.
