Hi Lindsay,

You've hit the system Exposé key assignments (keys F9, F10, and F11), and as a 
visually impaired user you want to disable these keys!  This will also remove 
the conflict between the Mac's key assignments for these keys and the Windows 
keys assignments under VMWare Fusion.  You can also disable the F12 shortcut 
for the Dashboard, and access it instead from the Dock (VO-d or Control-F3 to 
go to the Dock, then press "d", and open with space bar), or from Finder 
(Command-Shift-a to go to "Applications", press "d" for "Dashboard", 
Command-Down arrow to open).

To disable these key assignments, turn them off from the Keyboard menu in 
System Preferences:
1. VO-m or Control-F2 to the Apple menu, arrow down and press "s y" to go to 
"System Preferences", and press Return
2. Navigate (tab or VO-Right Arrow) to the "Keyboard" menu and press (VO-Space)
3. Navigate to the "Keyboard Shortcuts" tab of the "Keyboard" menu and select 
it (VO-Space)
4. On the "Keyboard Shortcuts" tab, navigate to the "Shortcuts Category" table, 
interact, and select the category you want to modify (e.g. "Dashboard & Dock" 
for the F12 key or "Exposé & Spaces" for the F9, F10, and F11 keys).
5. Stop interacting and navigate to the "Keyboard Shortcuts" table for that 
category and interact.  To turn off the shortcut assignment, navigate to the 
shortcut (e.g. "Dashboard" or "Exposé") and uncheck the checkbox with VO-Space. 
 Unchecking "Exposé" will uncheck all three Exposé key assignments, although 
you can also check or uncheck them individually.)
6. Quit System Preferences with Command-q

Briefly, the Exposé keys are a visual implementation of the Window Chooser menu 
(VO-F2 twice), like using an icon view instead of a list view in Finder.  Small 
thumbnail views of your active windows replace the icons, and the entire screen 
is used as the window for the icon display.  VoiceOver users who press the 
Exposé keys (Fn+F9, Fn+F10, and Fn+F11) generally think their screen has frozen 
or that VoiceOver has stopped working, because the system is waiting for you to 
select one of the windows to receive focus by moving your mouse cursor there 
and clicking.  You can get out of this mode by pressing the same keys again 
(e.g. Fn+F9, etc.), which will return you to whichever window had focus before 
you pressed the shortcut.  It's even worse if you happen to press the Shift key 
together with Fn+F9, etc. keys, because then the windows move into icon view 
mode in slow motion, and everything takes longer to respond.  The different 
F-key options are for switching between all active windows, all active windows 
of the current application, and for clearing aside the windows to view the 
Desktop.  I've written before to [email protected] with the suggestion 
that they default to disabling the Exposé shortcuts for users who set up their 
accounts to use VoiceOver.

The Dashboard (F12) may be useful to you.  This is the location for small 
widget programs that can be run on your Mac, such as for the weather, 
calculator, etc.   Some iOS programs have widget counterparts, although the 
widgets may not be as accessible as the iOS apps on your iDevices, as a general 
rule.

HTH.  Cheers,
