To resize a window in this program, click and drag any corner to make it larger or smaller. In Windows, to maximize, double-click the title bar or click the square box at upper right of the window. To restore to the former size after maximizing, double-click the title bar again or click the double-square box that has replaced the square box. This is normal Windows® procedure.
In Mac, click on the green circle to maximize and the red circle to close.
When using the Field Guide, all the information usually does not fit on the screen. You can use the QuickJumps to jump farther down the page or use the scroll bar or scroll button. You may also scroll up and down a page by using the scroll wheel on your mouse. A handy Windows feature for any scrollable display is to click in the topic, and then press ctrl+end to go to the bottom of the page, and press ctrl+home to go to the top.
