Scroll wheel support
You can use a pointing device (mouse) equipped with a scroll wheel with FileMaker Pro to browse through records, scroll up and down, and scroll in a field or portal formatted with a vertical scroll bar. In Windows, you can also change the magnification of the image on your screen (zoom in or out).
OS X: In Form View, hold the mouse cursor over the book or slider in the status toolbar, then rotate the scroll wheel. FileMaker Pro scrolls through records as if you were clicking the left and right pages of the book.
