APPLICATION NOTE #148
 USING XYWRITE WITH THE KEY TRONIC 5153 KEYBOARD
 Rev. 01


 The KB 5153 Touch Pad Keyboard, manufactured by Key Tronic 
Corporation, adds three specialized keys and a touch pad to the 
standard 84-key PC keyboard. This application note describes how the 
KB 5153 operates with XyWrite.


 NEW KEYS
 The KB 5153 has three new keys: Pause, Reset, and TouchPad. Each of 
these keys is described briefly below.

 In XyWrite, Pause performs the same function as NumLock. If you remap 
NumLock, you also remap Pause. (In DOS, pressing Pause stops a 
directory from scrolling so you can read it.)

 Reset works with Ctrl to perform a soft boot (the same function as 
Ctrl-Alt-Del on standard keyboards). You can also use the Reset key 
to synchronize the status of toggle keys with the LED indicators. To 
do this, press Reset with NumLock, ScrollLock, or CapsLock until the 
LED reflects the key's status.

 TouchPad toggles the touch pad on or off.

 These specialized keys cannot be remapped in a XyWrite keyboard file.


 THE TOUCH PAD
 The touch pad can operate in four basic modes: cursor mode, function 
key mode, mouse mode, and graphics mode. Each of these modes is 
supported by a different driver program, all of which are provided on 
the disks that accompany the keyboard.  Note that only cursor mode 
and function key mode work with XyWrite.

 When in cursor mode, the touch pad affects cursor movement.  If you 
drag your finger left to right, the cursor moves left to right. Both 
linear and regular cursor functions work well in XyWrite. Cursor mode 
is the default mode that is activated when you press TouchPad without 
loading a different driver.

 In function key mode, the touch pad is divided into programmable 
cells, similar to Save/Get keys. You can assign a keystroke sequence 
to each cell; the sequence can contain DOS commands, XyWrite 
commands, text strings, and even simple XyWrite programming. When you 
press one of the cells, you execute the keystroke sequence assigned 
to it.

 To program the touch pad cells, you use a software utility provided 
with the keyboard. You cannot program the cells by modifying the 
XyWrite keyboard file. By using the utility program, you can assign 
any XyWrite keystroke or keystroke sequence to a touch pad cell. 
Because you can just assign keystrokes, you can only execute those 
XyWrite function calls (such as BC) that are mapped to keys (such as 
F5).  For detailed instructions on programming the touch pad cells, 
refer to the Key Tronic Operator's Guide.

 You can combine cursor mode and function key mode so that one section 
of the touch pad toggles you between the two modes. For information 
on activating different touch pad modes, refer to the Key Tronic 
Operator's Guide.


 KEY CLICK
 The KB 5153 keyboard has a distinctive key click that can be disabled 
by pressing Ctrl-TouchPad. This key click setting is independent of 
the XyWrite key click setting.


 SYS REQ KEY
 SysReq is key 84 on the standard IBM keyboard. On the KB 5153 
keyboard, it cannot be mapped.
