-// This class is a convenience class for handling editor key bindings defined
-// in gtk keyboard theme.
-// In gtk, only GtkEntry and GtkTextView support customizing editor key bindings
-// through keyboard theme. And in gtk keyboard theme definition file, each key
-// binding must be bound to a specific class or object. So existing keyboard
-// themes only define editor key bindings exactly for GtkEntry and GtkTextView.
-// Then, the only way for us to intercept editor key bindings defined in
-// keyboard theme, is to create a GtkEntry or GtkTextView object and call
-// gtk_bindings_activate_event() against it for the key events. If a key event
-// matches a predefined key binding, corresponding signal will be emitted.
-// GtkTextView is used here because it supports more key bindings than GtkEntry,
-// but in order to minimize the side effect of using a GtkTextView object, a new
-// class derived from GtkTextView is used, which overrides all signals related
-// to key bindings, to make sure GtkTextView won't receive them.
-//
-// See third_party/WebKit/Source/WebCore/editing/EditorCommand.cpp for detailed
-// definition of webkit edit commands.
-// See webkit/glue/editor_client_impl.cc for key bindings predefined in our
-// webkit glue.
