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 ToolStripDropDownItem implementation of this method calls the ProcessCmdKey of the DropDown if there are items in the DropDownItems collection. Otherwise, this implementation calls the base class implementation.

Notes to Inheritors:

When overriding the ProcessCmdKey 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.

SecurityPermission

for the immediate caller and inheriting classes to call this method. Associated enumeration: SecurityPermissionFlag::UnmanagedCode.
