The QuicKeys Edit menu has a single command: Preferences. Use this command to select either of the following preferences when you run QuicKeys:
Minimize QuicKeys when you first run it (select Minimize QuicKeys When Opened) or run it in its normal window (leave Minimize QuicKeys When Open clear).
Perform searches for all books in one Viewer window (select Use One Viewer Window Only) or run a separate instance of the Viewer for each book in which you search (leave Use One Viewer Window Only clear).
