Hi Eleanor,

As a modification of Sarah's suggestion, can you use Mouse Keys to click the 
buttons for "accept" and "play", with VoiceOver turned off if necessary, in 
order to use the web site without crashing?  If the crash is caused by 
VoiceOver's software simulation of key clicks with VO-Space or VO-Shift-Space, 
using Mouse Keys to click for you (by pressing the "i" key on a laptop 
keyboard, or Control+the "5" key on the numeric keypad of a full-sized keyboard 
after Mouse Keys are turned on) might work without your even having to toggle 
VoiceOver off  before you click. 

Are both buttons for accept and play displayed on the same web page?  If so, 
you can move to these controls without actually clicking the buttons first with 
VoiceOver, check their screen locations with VO-F5-F5, then figure out how many 
Mouse Key key presses are needed to move from one control to the other (without 
VoiceOver), turn VoiceOver off, and perform these actions with Mouse Keys on 
(but VoiceOver off).  Perhaps once play has started you can turn VoiceOver back 
on again.

You will need to go to System Preferences > Accessibility and select "Mouse & 
Trackpad" in the accessibility features table, then instead of simply checking 
the "Enable Mouse Keys" check box, navigate to the "Options" button and press 
it, then check the box for "Press the Option key five times to toggle Mouse 
Keys" and press return (or navigate to the "Done" button).  This will let you 
toggle mouse keys on or off by pressing the Option key 5 times.

Mouse Keys are designed to allow people with motor disabilities to perform 
precise actions requiring fine control, such as moving  mouse cursors or 
clicking their mouse or trackpad, with keyboard controls.  I've only used it 
with VoiceOver in a few situations.  The first is when a physical mouse click 
with trackpad or cursor is required.  The VO-Shift-Space shortcut is a 
simulated mouse click implemented by software.  The VO-Space shortcut is 
another software defined shortcut that performs the default action -- which 
could be pressing a button, clicking on link, selecting a menu option, etc. 
depending on context.  There are some instances, especially in situations where 
applications are not fully accessible or are transitioning in accessibility 
with VoiceOver, where these kinds of "software" clicks do not work, and you 
have to physically click your trackpad or mouse for your click to take effect.  
In these instances, performing a click with "Mouse Keys" mode turned on is equi
 valent to physically clicking with mouse or trackpad.  The NumPad Commander 
keyboard shortcut for a key click, of Control + "5" on the numeric keypad will 
also work. It's possible the software emulation of your keyclicks is causing 
your crashes, so either performing a click with Mouse Keys, even with VoiceOver 
turned on, might solve your problem.  And if having VoiceOver after the key is 
pressed causes your crash, you might be able to move to each control and press 
it entirely using Mouse Keys but keeping VoiceOver turned off.

In addition to allowing users to click a mouse or trackpad without moving the 
position of the mouse pointer, Mouse Keys mode lets you move the mouse pointer 
position on the screen in pixel increments by using key strokes.  So the second 
circumstance in which I've used Mouse Keys is for instances when I need to move 
the mouse pointer to locations that VoiceOver doesn't navigate to, in order to 
click on controls.  The most common example of this usage is when trying to 
deal with flash controls on a web page.  VoiceOver can't "see" these controls, 
in the sense that you can't use VoiceOver commands to navigate to them, since 
Adobe's Flash does not comply with Apple's accessibility API.  However, if you 
manage to move your mouse pointer over a flash control independently of using 
VoiceOver's cursor, because you've turned cursor tracking off (with 
VO-Shift-F3), VoiceOver can tell you what is under your mouse pointer (with 
VO-F5, or by checking the box for "Speak text under mouse after delay" in the 
"Announcements" tab of "Verbosity" in VoiceOver Utility) and will even describe 
the screen coordinate location of your mouse pointer (VO-F5-F5 or VO-F5-F5-F5).

So the way I used to play the Audible audio book sound samples before they 
changed their web pages from Flash only to HTML 5 versions was by navigating to 
"Sample" with VoiceOver, then turning keyboard tracking off, and Mouse Keys on, 
and moving the mouse pointer 50 pixels to the left of "Sample" so that the 
player control was under the mouse pointer.  Then I would click to start the 
sample playing.  On extended keyboards, Mouse Keys uses the numeric keypad, 
with the central "5" key to designate the current position of the mouse.  To 
move the mouse pointer 1 pixel to the left, you press the key the left of the 
"5" key once, and similarly if you want to move to the right, up, down. or 
diagonally.  You use the nine number keys (1-9, with 5 in the central 
position), to move your cursor, pixel by pixel.

On a laptop keyboard, the keys you use are where the embedded numeric keypad 
used to be -- surrounding the "i" key.  So "j k l" was "1 2 3", "u i o" was "4 
5 6", and "7 8 9" (on the top row of number keys) was "7 8 9".  To move to the 
left I tap the "u" key with Mouse Keys on. To move to the right I tap the "o" 
key.  And to click my "mouse" I tap the "i" key when Mouse Keys are turned on.

Note that you can also move your mouse pointer using the trackpad (when 
TrackPad Commander in turned off) if cursor tracking is turned off. If you have 
the box checked for "Speak text under mouse after delay" in the "Announcements" 
tab of "Verbosity" in VoiceOver Utility, you'll also be told what is under the 
mouse. (You may want to adjust the slider to make the time delay short).  This 
does not require using Mouse Keys at all.

To announce the position of your mouse cursor, you can use VO-F5-F5 or 
VO-F5-F5-F5.  (The first gives coordinates with respect to the top left corner 
of your screen, the second gives coordinates with respect to the top left 
corner of your window).  To use this feature, I also set my VoiceOver Utility 
Verbosity > Announcements tab so the pop up following  "Speak size and 
position" is set to "points" instead of "inches" or "millimeters".  Then the 
announced coordinates are pixels on the screen.

If you can figure out how many pixel key presses in the x and y direction to 
move between the two controls you need to press, you only have to work this out 
once, and  then use Mouse keys to move to the screen controls and perform the 
click (even with VoiceOver off). It's a pain to press a key 50 or 60 times, but 
at least it works.

HTH.  Cheers,

Esther
