Searching KWIC from Browse Window
That's a great idea. I've put in a plug for its inclusion in the program. I can't say if or when it can be implemented, as we are all very busy right now.
Simply copying Greek text from the Browse Window to the Command Line or to the KWIC module doesn't work because searching on Greek accents is off by default. Place your mouse on the Command Line and right-click to open the Command Line context menu, and select Accent Sensitive Search (Greek), and then it will work. Of course, then you have to include the proper accents in all your Greek searches until you uncheck the accent sensitive searching.
