What is the enum for - (minus/underscore) and = (equal/plus) key in Keys enumeration?

Question

I can't seem to find them here.

I'm trying to get them include in my hotkey selection dialog.

Answer 1

Would OemMinus and OemPlus work for you?

Answer 2

Checkout Oem*, from the link that you provided:

OemMinus    The OEM minus key on any country/region keyboard (Windows 2000 or later). 
Oemplus     The OEM plus key on any country/region keyboard (Windows 2000 or later). 

You can have something like:

if (keyData == (Keys.Control | Keys.OemMinus) ) ZoomOutOrSomething();//
