jQuery Grid Plugin - jqGrid

There is a method used when doing cell editing called editCell that requires you to pass in iRow and iCol.  How can I get iRow and iCol for the cell I want so that I can programatically call this method?  It seems the only way to get these values is via an event firing on the grid, but what if I want to use my own button somewhere else to manipulate the grid?

For instance I want to select a cell or edit a cell based on a button press in some other part of the page.

My main problem is that I want to add a row to the grid, but I have cell editing enabled, so I can't select the new row with the setSelection method because then clicking on any other cell in the grid leaves the other row selected.

I enabled Cell Editing so that when a user clicks on a particular cell I can fire an event based on what they clicked using onSelectCell.
