Hi,
it is a matter of cell editing and cell selection.
If I start editing with a double click and press the Enter key, the selection stay in the cell.
BUT.
If I start editing with another key (but neither Ctrl nor arrow key) by startEditing(rowNum, colNum, suppressFocus) and then press the Enter key, the selection vanish and I need to set a new one.
What can I do?
I adapted example from Showcase:
Thank you in advance,
