HOW TO: Add + Clear Widgets.

You recently learned how to use the dashboard and its widgets (see last post). Apple provides some as default in the system, but you can:

a) add a widget by downloading one on the many sites. Once the file "calculator.widget" has been downloaded it can be installed by simply double-clicking on it. It will open in the dashboard asking if it has to be "keeped". Click ok and there it is.
You can also add some others by clicking on the "+" sign on the bottom-left corner of the screen. They are available in the system but not present in your actual dashboard.

b) delete the widgets by simply pressing the ALT-OPTION key while hovering with the mouse on the widget you want to close, then click on the black "X" on the upper-left corner of this widget.
