Hi, I would propose a change to this dialog (qt). ATM there is a checkbox for searching backwards. I think this is awkward, because you need two clicks. Also you always have to make sure you search in the right direction.
How about two buttons? A button 'Search forward' and another button 'Search backward'? This would also be consistent with the bibtex citation dialog, where you find this solution. Thanks, -- Moritz Moeller-Herrmann
