I have a Microsoft ergonomic keyboard 4000. In Firefox 3.6, the zoom slider on the keyboard worked as a scroll wheel in Firefox. After upgrading to Firefox 4, the slider is back to the zoom function. I have tried several "hacks" and the slider acts as a scroll wheel in every program except FF.

Firefox 4 changed the window class from MozillaUIWindowClass to MozillaWindowClass.


  1. In MS Windows kill the "itype.exe" process.
  2. Open the command.xml file with your favorite editor as Administrator
  3. Locate the UniqueName="MozillaWindowClass" AppName="Netscape" in the parent element "All". Mine was line 2967.
  4. Change the KeySeq="ctrl add" and KeySeq="ctrl subtract" to KeySeq="pageup" and KeySeq="pagedown" respectively.
  5. Start >> Run >> itype.exe

You can leave the everything else the same for backward compatibility.

Note that the patch above changes the behavior of the MS Ergo 4000 keyboard "Zoom" control to "PageUP" and "PageDown"! That is not the same as "ScrollUp" and "ScrollDown". The former will move the screen a page at a time, rather than a single line. The "Scroll" hack is still broken with Firefox 4.

If you want ScrollUp and ScrollDown you need to change

<C319 Type="5" KeySeq="ctrl add" />

<C320 Type="5" KeySeq="ctrl substract" />

to :

<C319 Type="6" KeySeq="ScrollUp" />

<C320 Type="6" KeySeq="ScrollDown" />
