Recently I bought Microsoft Natural Ergonomic Keyboard 4000.

Microsoft® Mouse and Keyboard Center allows to remap/assign some specific keys, but some keys like central "star" button, or zoom in/out button cannot be reassigned, but only enabled/disabled.

I tried to reassign these keys using Sharpkeys, but this program does not recognize them: if I type these keys it do not show anything is type mode.

If I run Microsoft keyboard diagnostics and type these keys there, they are displayed as "HID Input" without any keycode.

So is there any way to remap/assign star and zoom in/out keys?

  • Did you ever find a solution to this?

The Zoom key can be mapped to scroll up or down as can be seen here it's very useful and is working on Windows 7, 10 (I didn't try on Windows 11).

Regarding the star key I did not manage any way to remap it.


The latest 2023 solution that worked was to simply update the command file for the two key actions related to zoom and make them scroll in the commands.xml file at C:\Program Files\Microsoft Mouse and Keyboard Center, in the section.

  <C319 Type="6" Activator="ScrollUp" />
  <C320 Type="6" Activator="ScrollDown" />
