Special Settings
Apple Key Positions on the Windows Keyboard
The Y-mouse comes configured for normal operation on the vast majority of computer
systems, but also has a number of special settings programmed in its firmware. To access
these settings, plug a PS/2 keyboard into the Y-mouse. To see which settings are active
on the Y-mouse open a text editor (Notepad, or SimpleText for example).
Press and hold the “Esc” key, press and release the “S” key, and release the “Esc” key.
The Y-mouse will report its firmware version and settings to the computer. For example
“v3.12[w]” means Firmware Version 3.12 with the “W” setting active.
These settings are memorized and remain active even if the Y-mouse is unplugged or
moved to another system. To turn on or off any of the special settings use a keyboard
connected through the Y-mouse and press and hold the “Esc” key while pressing and
releasing the key for that setting.
<Esc + E> Stops the normal USB power-off feature. Set this if you want to use the
attached mouse and keyboard to wake up the computer. After executing this command,
unplug and re-plug the Y-mouse from the USB port or restart your computer to make this
special setting take effect.
<Esc + F> Eliminates the keyboard timeout feature to allow keys to be held down longer
than 20 seconds.
<Esc + P> Scandinavian key code conversion. Changes the scan code for the (pipe
character) key. This affects UNIX work stations and some foreign keyboards.
<Esc + Q> Sets the mouse speed to a faster mode.
<Esc + T> Allows the operating system to control the “Num Lock” indicator.
<Esc + Y> – Sets the Scroll Lock key as a USB scroll lock. (Default mode uses Scroll
Lock as the Apple “Power off” key).
When using a Windows keyboard on an Apple computer, the Windows key is translated
as the Apple Command key. Since Apple keyboards and Windows keyboards have
different positions for the Alt/Option and Win/Command keys, the Y-mouse offers two
special settings to control the position of those keys to suit the user (please see the
following table).

Toubleshooting
The Y-mouse uses the standard USB mouse and keyboard drivers already on the
operating system. Special drivers or software for PS/2 keyboards and pointing devices
may not be supported. Test each device independently without the Y-mouse to confirm
that each will operate on the computer. Please contact our technical support department
for help:
