You can protect picture from deletion:

rve.Clear;

rve.AddPictureEx('', Graphic, 0, rvvaBaseline);

rve.SetItemExtraIntProperty(rve.ItemCount-1, rvepDeleteProtect, 1);

rve.Format;

Process OnKeyDown, check if Key=VK_RETURN, and assign Key:=0 to prevent the

defalut processing of Enter.

Note: not all operations can be performed just inside OnKeyDown. If the

caret is in a table cell, you cannot call methods that move caret outside of

it or delete this cell. If you need it, use PostMessage.
