Grid autopaging when controlled by UP and DOWN arrow keys

I was looking at this demo for keyboard interaction with grid - this is awesome functionality!

What I would like to achieve is to be able to use only UP and DOWN arrow keys to navigate through whole grid. Problem is that once I reach last record on the page I have to press PgDown to move to the next page.
Is there any way to enable automatic paging? I mean that once I will be on lat record for given page, next press of down arrow key will bring mi to the first record of next page (sp I will not have to press PgDown).

I think this will be much more user friendly :)

Hi Tom, 

Thanks for contacting Syncfusion support. 

To achieve your requirement, we used keydown event and RowSelected event of ejGrid.  when we press the down arrow key on the last record the keydown event will be triggered. In this event we check the condition with PageCount and rowIndex to navigate to the next page. 

Find the code example: 

        .EditSettings(edit => { edit.AllowEditing().AllowAdding().AllowDeleting(); }) 
        .Columns(col => 
        .ClientSideEvents(eve => { eve.RowSelected("rowselect"); }) 

    var select = true; 
    $(document).on("keydown", function (e) { 
        if (e.keyCode == 40 || e.keyCode == 38) { 
            var grid = $("#Editing").ejGrid("instance"); 
            var pageIndex = grid.model.pageSettings.currentPage; 
            var rowindex = grid.getIndexByRow(grid.getSelectedRows()); 
            rowindex = rowindex + 1; 
            if (rowindex == grid.model.pageSettings.pageSize && select) { 
                $("#Editing").ejGrid("getPager").ejPager("goToPage", pageIndex + 1); 
            else if (rowindex == 1 && select) { 
                if (grid.model.pageSettings.currentPage != 1) { 
                    $("#Editing").ejGrid("getPager").ejPager("goToPage", pageIndex - 1); 
            select = true; 
    function rowselect(args) { 
        if (args.prevRowIndex = this.model.pageSettings.pageSize - 2) 
            select = false;
