SpecialKey (Enum)

The SpecialKey Enum for the AddSpecialKey method has 6 types:
Enum	Name	Description
0	Insert	The enum value for the insert key.
1	Home	The enum value for the home key.
2	End	The enum value for the end key.
3	PageUp	The enum value for the page up key.
4	PageDown	The enum value for the page down key.
5	ChatHotkey	The enum value that represents the chat hotkey. ("\")

Most of these values do not appear to work with AddSpecialKey, however, the ChatHotkey enum does work when no special keys, like shift or control, are down.
