If I add some text to a field cell (e.g. item field) by typing it into the field, and then press the down key to move down one cell, the added typed text gets saved.   Even though I did not press Enter to save the edits.

However, if I Ctrl+V paste some additional text into the field (e.g. a link), and then press the down key to exit the cell, without first pressing the Enter key, the pasted text does not get saved.  Pasted text gets saved only if I press Enter.

So my suggestion, for sake of consistency, is to save the pasted text if the cell is exited with an arrow key without pressing Enter first.
