How to programmatically page to next/prev page in jqGrid

Question

Is there a jqGrid method that will skip to the next/prev page of rows. I was trying to programmatically click the button itself with jQuery, but didn't succeed yet

Answer 1

To go to page 123:

grid = $("#grid");
grid.setGridParam({
    page: 123
});
grid.trigger("reloadGrid");

NB: The grid behaves oddly if you go to a page for which there is no data.
