Window.getAttention() method attempts to get the
user's attention. The mechanism for this happening depends on the specific operating
system and window manager.
On Windows, the taskbar button for the window flashes, if this hasn't been disabled by the user.
On Linux, the behavior varies from window manager to window manager - some flash the taskbar button, others focus the window immediately. This may be configurable as well.
On Macintosh, the icon in the upper right corner of the desktop flashes.
The function is disabled for web content. Neither Gecko nor Internet Explorer supports
this feature now for web content.
getAttention will still work when used
from chrome in a Gecko application.
