Get Mouse Wheel Display name

I am working with Rama’s plugin to rebind keys, everything seems to be working fine for the most part. It overrides OnKeyDown to get the new key, which works (with exception of space bar), and overrides OnMouseButtonDown to get mouse buttons, which works with exception of left mouse button)… But my problem, or question, is the mouse wheel…

For mouse events you can connect the ‘Mouse Event’ to a GetEffectingButton to get the Key structure, then pass that to a ‘Key Get Display Name’ and it returns a text of the button pressed (for OnMouseButton) such as ‘Right Mouse Button’… But with the Mouse wheel, ‘Key Get Display Name’ returns ‘None’, for mouse wheel up and mouse wheel down.

Am I missing something or is that bit just not ‘done’?
