Select the eighth beat label by clicking left or right, or using the arrow keys, until the selection rectangle surrounds it. Change the `N' to an `A' by clicking the middle button or pressing . (On some keyboards, if `Num Lock' is off, you can use the key on the numeric keypad instead of if you prefer.) The `N' is
replaced by an `A' and the selection rectangle disappears. To indicate that there are unsaved edits in the annotation file, the annotator name in WAVE's main window title bar is marked by parentheses.
