Browse Window Scrolling Shortcuts
The Browse Window has several shortcuts to facilitate browsing through text. There are three different scroll modes. To change the scroll mode place the mouse over the Browse Window and click with the Left Mouse Button. Then press: Ctrl + Shift + á (the up arrow key). As you press this key combination three times you will see the current scroll mode shown the in Information Window in lower left hand corner of the BibleWorks Screen. The three scroll modes are:
Non Synch mode
In this mode the up and down arrow keys will cause the Browse Window to go backwards and forwards one verse.
This is the same as the previous mode, but all open Browse Windows will be scrolled as well.
Scroll Mode Off
This is the default mode. The up and down arrow function as navigation keys within the Browse Window.
