Configuring the Mouse Wheel

You can enable or disable the use of  the mouse wheel.  You can also specify the key function to be used when the mouse wheel is rotated up or down.  The mouse wheel is disabled by default.

This feature is only available when you are running Z and I Emulator for Web on a Java 2 JVM 1.4 and later.  Also, this feature is only available on display sessions such as, 3270 Display, 5250 Display, CICS and VT sessions.

Select the Enable Mouse Wheel checkbox to enable this feature, and use the Settings to specify key functions.  The Setting options include the following:

Page Up
Expand the dropdown menu to select the key functions available for page up.  The choices available depend on the type of session you are running and include the following: 

3270 and CICS Sessions:
PF1-PF24, PA1-3, Enter, and Attn

5250 Sessions:
Page Up, Page Down, PF1-PF24, and Enter 

VT Sessions:

If you are using ThinkPad TrackPoint on Windows, mouse wheel might not work due to the functional limitation of Java. This problem can be worked around with the following procedure:
  1. Open the tp4table.dat file in your text editor, for example, Notepad.exe. The tp4table.dat file is typically found in the C:\Program Files\Synaptics\SynTP directory.
  2. Locate the following lines:
    ; Java support
    *,*,java.exe,*,*,*,WheelStd,1,9
    *,*,javaw.exe,*,*,*,WheelStd,1,9
  3. Add the following lines after the lines located on step 2:
    *,*,*,*,*,SunAwtCanvas,WheelStd,1,9
    *,*,*,*,*,com.ibm.eNetwork.HOD.SessionFrame,WheelStd,1,9
  4. Save the change and reboot the system
