When you first begin using Accounting Plus, the program is set up so that if you press the ENTER key, you'll click the default button (the button with a dark border around it). If you'd rather press the ENTER key to move between fields in Accounting Plus windows, mark the box in this step. (If you mark this selection, you still have the option to use the TAB key to move between fields.)
