It is required toı change default UltraWebGrid action response against ENTER key.

Normally after writing something  in a cell and pressing ENTER , the selected cell will be changed to the right cell of it. I want ENTER key to select the cell immediately below that and TAB key to select the one immediately the right and BACKSPACE immediately the left of it.

I try to control it through keydown, keyup and afterexitedit , manage to change the behaviour in IE but not FIREFOX.

What event combinations and correct orders should be used to perform that change OR

is there any other way - such as configuration option or the grid component etc - to make it possible more easily???
