Dhtmlx Grid: highlight current cell

Is there a quick way to highlight the current cell in the grid?

The grid has predefined css rule for selected cell, which can be changed in dhtmlxgrid.css

div.gridbox table.obj tr.rowselected td.cellselected, div.gridbox table.obj td.cellselected {
    background-color:#d8d8d8;
    color:black;
    }
( Actually there are few similar rules - for different skins )

If necessary, the currently selected cell can be accessed as grid.cell from js code
    if (grid.cell) grid.cell.className=“selected”
