jQuery Grid Plugin - jqGrid

Hi all,

one question for all advanced in jqgrid.

i have to code this usecase:

In jqGrid there are two editable columns. I have to use cell editing.

User click to one editable cell and when he presses 'Enter' key, i select next editable cell UNDER actual one. Otherwise, when he hits 'tab' key, i select next editable cell - if actual cell is last, i set the nearest editable cell in the next line or if not, i select next editable cell in the actual row. - to sum up - i need exact behaviour like in excel.

to better imagination i added image with simple instructions.

thanks a lot.
