The ::change-value signal is a [keybinding signal]GtkBindingSignal which gets emitted when the user initiates a value change.
Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically.
The default bindings for this signal are Up/Down and PageUp and/PageDown.
