Well, I'm glad Diogenes isn't only quirky with me.
Thanks, anantah, for the ctrl-C tip. Why didn't I think of that myself?
Overall, Diogenes feels a bit primitive as far as its user interface goes. For example, it only offers Next Entry and Prevous Entry. Since the dictionary contains trillions of words (a plus in itself) it takes ages to step through to what you thought might lie just around the corner. And then you have to step all the way back again, Previous Entry by painful Previous Entry! Would it have been so difficult for them to include a PageDown/PageUp or a Home button? Or a scrolling list? Or is there some magic key combination for these functions too?
But perhaps it's mean-spirited of me to be so picky, considering Diogenes provides such wondrous resources - and all for free! Perhaps it's up to me the user to find a way of taming the beast.
