_focusrect = Boolean;
Specifies whether a yellow rectangle appears around the button or movie clip that has keyboard focus. If _focusrect is set to its default value of true, a yellow rectangle appears around the currently focused button or movie clip as the user presses the Tab key to navigate through objects in a SWF file. Specify false if you do not want to show the yellow rectangle. This is a property that can be overridden for specific instances.
If the global _focusrect property is set to false, the default behavior for all buttons and movieclips is that keyboard navigation is limited to the Tab key. All other keys, including the Enter and arrow keys, are ignored. To restore full keyboard navigation, you must set _focusrect to true. To restore full keyboard functionality for a specific button or movieclip, you can override this global property by using either Button._focusrect or MovieClip._focusrect.
Note: If you use a component, FocusManager overrides Flash Player's focus handling, including use of this global property.
Note: For the Flash Lite 2.0 player, when the _focusrect property is disabled (such as Button.focusRect = false or MovieClip.focusRect = false ), the button or movie clip still receives all events. This behavior is different from the Flash player, for when the _focusrect property is disabled, the button or movie clip will receive the rollOver and rollOut events but will not receive the press and release events.
Also for Flash Lite 2.0, you can change the color of the focus rectangle by using the fscommand2 SetFocusRectColor command. This behavior is different from Flash Player, where the color of the focus rectangle is restricted to yellow.
The following example demonstrates how to hide the yellow rectangle around any instances in a SWF file when they have focus in a browser window. Create some buttons or movie clips and add the following ActionScript in Frame 1 of the Timeline:
_focusrect = false;
_focusrect (Button._focusrect property), _focusrect (MovieClip._focusrect property)
