		171	click) and is either supposed to return false (normal operation), or
		172	should extend the selection itelf and return true to suppress the built-in

		210	operating system command) is processed. Cursor position and other state
		211	information is up-to-date when this happens. For interoperability, the

		224	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		225	might be very slow, however, as your hook is called for B<all> text being
