Gtk.TextView::move-viewport

function callback(text_view, step:Gtk.ScrollStep, count:Number, ):void;

The ::move-viewport signal is a <link linkend="keybinding-signals">keybinding signal</link> which can be bound to key combinations to allow the user to move the viewport, i.e. change what part of the text view is visible in a containing scrolled window.

There are no default bindings for this signal.
