I'm currently using Bibleworks 6, but 7 is on its way to me, so you can respond for either version.
Two things I've been looking for:
1. A control key sequence that will jump me directly to the command line, rather than having to click on it? If I'm using Bibleworks while taking notes for a class, I would prefer to interact with it through the keyboard. The only thing I need to know to do that is how to move to the command line through some shortcut.
2. Is there a way to clear search results? I can be sort of OCD, and when I've found something I'm looking for, I prefer not to have the text highlighted.
