· Window-Eyes hot keys can be modified under the Hot Keys dialog in the Window-Eyes voice control
panel. All Window-Eyes hot keys are defined in Appendix A of the Window-Eyes manual.
2. Desktop Versus Stand Alone Application
Window-Eyes can be accessed by logging on to a published desktop, or by using Window-Eyes as a
published application (depending on the configuration of the Citrix MetaFrame XP server). During a
remote desktop session, Window-Eyes will interact with any other application launched in the same
desktop area. As a published application (not accessed through a remote desktop session), Window-
Eyes will only interact with other published applications launched in the same client's unique session.
For example, if Window-Eyes and Microsoft Internet Explorer are both shared applications, and the
client runs both applications during a unique session, Window-Eyes will be able to read and interact
with the Microsoft Internet Explorer window. Running Window-Eyes as a published application will not
read any local application that is run on the client device. Running Window-Eyes remotely through
Citrix MetaFrame XP will only allow speech access to other remote applications run under the same
unique session. Your local copy of Window-Eyes, however, can be used to interact with your local
applications.
It is important to note that, while running Window-Eyes as a remote application, and as a local
application, you will have two instances of Window-Eyes on the taskbar at one time. You will be able
to tell the difference by examining the names of the applications.
3. Interacting with Other Applications
After a user initiates a Citrix MetaFrame XP session and is running Window-Eyes successfully, the
interaction between Window-Eyes and any installed application will work identically to running
Window-Eyes on a stand alone machine with that same application. For example, Window-Eyes
keystrokes, hot keys, and reading options for Microsoft Internet Explorer will work the same whether
Window-Eyes is running locally or through a remote Citrix MetaFrame XP session.
4. Multiple Window-Eyes sessions
Multiple users can run Window-Eyes under their own unique sessions with no conflicts with other
instances of Window-Eyes running remotely in Citrix MetaFrame XP sessions.
Running Window-Eyes Locally on Server
Window-Eyes can be run on the Citrix MetaFrame XP desktop with no conflicts with other instances of
Window-Eyes running remotely in Citrix MetaFrame XP sessions.
Remote Access Caveats
1. Software Speech
At the time of this documentation, support for SAPI speech synthesizers in a remote Citrix MetaFrame
XP session is somewhat lacking. Although the voice quality can remain tolerable, the responsiveness
(even over high bandwidth network connections) can lag behind up to two seconds behind a given key
press. For a solution to this problem, review the Window-Eyes Virtual Synthesizer option listed in the
Server-Side Configuration section.
2. Hot Key Conflicts
Window-Eyes users are often comfortable with the Windows hot keys (such as CTRL-ESC, ALT-
TABB, etc.) that allow them easy access to commonly used areas in the operating system. Pressing
these keys during a remote session will most likely cause the intended action to execute locally rather
than in the Citrix MetaFrame XP session. It is important to note the Important Hotkeys section of the
Running Window-Eyes Remotely section listed above.
3. Citrix MetaFrame XP Management Console
At the time of this documentation, the Citrix MetaFrame XP Management Console application
(available only to the Administrator of the Citrix MetaFrame XP server) is written in Java. Window-
Eyes, currently, does not support the Java language interface, and therefore does not provide access
to the Citrix MetaFrame XP Management Console.
4. Window-Eyes Local Versus Window-Eyes Remote
If a user runs Window-Eyes on a client device while at the same time running the Citrix ICA Client
software, Window-Eyes will remain loaded, but in a suspended state. This will eliminate any hot key
conflicts between the local copy of Window-Eyes and remote copy of Window-Eyes. To communicate
with the local copy of Window-Eyes, or other local applications, the user will need to ALT-TABB out of
the Citrix ICA Client to switch activation from the Citrix ICA Client to the local desktop. Window-Eyes
will no longer be suspended once activation has left the Citrix ICA Client. Closing the Citrix ICA Client
will also result in the local desktop regaining activation. It is possible, even after pressing ALT-TABB to
move activation to the local desktop, for the remote copy of Window-Eyes to send information to the
local copy of Window-Eyes through the Window-Eyes Virtual Synthesizer feature. This may cause
some speech to bleed through.
