public enum Keys
Remarks
The System.Windows.Forms.Keys class contains constants for processing keyboard input. The members of the Keys enumeration consist of a key code and a set of modifiers combined into a single integer value. In the Win32 application programming interface (API) a key value has two halves, with the high-order bits containing the key code (which is the same as a Windows virtual key code), and the low-order bits representing key modifiers such as the SHIFT, CONTROL, and ALT keys.
Do not use the values in this enumeration for combined bitwise operations. The values in the enumeration are not mutually exclusive.
This enumeration provides no way to test whether the CAPS LOCK or NUM LOCK keys are currently activated. You can use one of the following techniques to determine if these keys are activated:
Call the Control.IsKeyLocked(Keys) method of the System.Windows.Forms.Control class.
For finer control, use the Win32 API functions GetKeyState, GetAsyncKeyState, or GetKeyboardState defined in user32.dll, to do this. For more information about calling native functions, see Consuming Unmanaged DLL Functions.
The following table shows the key code values represented by two enumerated values, representing both the general original equipment manufacturer (OEM) keys and the more specific U.S.-keyboard associations.

For the .NET Framework 2.0, a member Keys.IMEAccept was added that supersedes the previous entry, Keys.IMEAceept, which was spelled incorrectly. The older version has been retained for backward compatibility, but it may be deleted in future versions of the .NET Framework
