IGV uses Netbeans QuickSearch module in the toolbar. QuickSearch comes with a default shortcut (Ctrl - I). To make the QuickSearch module visible in different graph tabs a "Workaround" was used to make a copy of the module (search module should be global and only one instance should exist). Because of this "Workaround" the shortcut does not work anymore. Fix the shortcut and best also change it to "Ctrl - F"
