The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     focus
 
     The item that is the immediate object of interaction in a user
     interface. When you shift the focus to a new item, the item is
     said to "gain the focus."
 
     A window with the focus is called the "active window." When a
     window gains the focus:
 
       ■  The cursor appears in the window.
 
       ■  The window appears on top of all other windows.
 
       ■  Scroll bars appear in the window border.
 
     When a button gains the focus:
 
       ■  The angle brackets surrounding the button name are
          highlighted.
 
       ■  The cursor appears on the first letter of the button name.
 
       ■  Press ENTER to activate the button.
 
     When a text box gains the focus:
 
       ■  Text in the box is selected.
 
       ■  The cursor appears at the end of the selected text.
 
     When a set of option buttons gain the focus:
 
       ■  The cursor appears within the parentheses on the selected option.
          The selected option has the bullet (•).
 
       ■  Press SPACEBAR, UP ARROW, and DOWN ARROW to select each option
          in turn.
 
     When a check box gains the focus:
 
       ■  The cursor appears within the brackets ([]).
 
       ■  Press SPACEBAR to toggle the state of the option. The letter X
          appears between the brackets ([X]) when the option is turned on.
 
     When a drop-down list box gains the focus:
 
       ■  Text in the edit box is selected.
 
       ■  Press ALT+DOWN ARROW or ALT+UP ARROW to open the list.
 
       ■  Press ALT+DOWN ARROW or ALT+UP ARROW to close the list.
 
       ■  Press UP ARROW and DOWN ARROW to select an item in the list.
