It sounds like you're hooking the KeyPress event instead of the KeyDown
event. That's why you get a KeyChar instead of a KeyCode and it also might
be why the code isn't working as you expect.
I can get the Keys enumeration just fine:
IronPython 2.6 Beta 1 DEBUG (126.96.36.199) on .NET 2.0.50727.3053
Type "help", "copyright", "credits" or "license" for more information.
>>> import clr
>>> from System.Windows.Forms import Keys
<System.Windows.Forms.Keys object at 0x000000000000002B [Return]>
