Tab - save and go edit next cell. If used in the last cell in current row, goes to first cell in next row. If there is no next row, it's created and first cell is focused.
Shift + Tab - save and go edit previous cell. If used on the first cell in current row, goes to last cell in previous row if it's possible.
Enter - save and stop editing.
Esc - stop editing without saving.
Note that with this system one cannot select the checkbox with keyboard while editing (they'd have to hit Esc first, then start selecting). I don't think this is a problem.
