This method is called during message preprocessing to handle command keys. Command keys are keys that always take precedence over regular input keys. Examples of command keys include accelerators and menu shortcuts. The method must return true to indicate that it has processed the command key, or false to indicate that the key is not a command key.

The base-class implementation of ProcessCmdKey method returns false in all cases.

Notes to Inheritors

When overriding the ProcessCmdKey(Message, Keys) method in a derived class, the method override should return true to indicate that it has processed the key. Derived classes will seldom, if ever, need to override this method.
