How do I search for all the occurance of ὁ in a interlinear bible? Is it possible?
If you mean a 'normal' interlinear bible, just find a ὁ, right-click on it, make sure 'Lemma' is selected in the right-hand part of the menu, and choose 'Search this resource'. You can do the same in a reverse interlinear, although it's a bit harder to find a ὁ. If so, you can just do a morph search, and type lemma:ὁ as the criteria.
