The main Crystal Ball menubar and menu commands are accessed with shortcut keys. After a menu is open, the Tab key or Down Arrow key highlights commands in a circular sequence (tabbing from the last item moves focus to the first item). Using Shift+Tab or the Up Arrow highlights commands in the opposite direction.
Default tab order in the Crystal Ball dialogs flows from left to right, top to bottom. Tab can be used to access the first item of a subwindow in a dialog, but then arrow keys are needed to move to additional items. For example, in the Distribution Gallery, Alt+b displays six basic distributions and places the focus on one of them. Using one of the arrow keys moves focus to an adjacent distribution. Tab moves focus to the OK button at the bottom of the dialog.
