// AutocompleteTextFieldEditor customized the AutocompletTextField
// field editor (helper text-view used in editing).  It intercepts UI
// events for forwarding to the core Omnibox code.  It also undoes
// some of the effects of using styled text in the Omnibox (the text
// is styled but should not appear that way when copied to the
// pasteboard).

// AutocompleteTextFieldEditorDelegateMethods are meant to be similar
// to NSTextView delegate methods, adding additional intercepts
// relevant to the Omnibox implementation.

@protocol AutocompleteTextFieldEditorDelegateMethods

// Delegate -paste: implementation to the field being edited.  If the
// delegate returns YES, or does not implement the method, NSTextView
// is called to handle the paste.  The delegate can block the paste
// (or handle it internally) by returning NO.
