Figure 12 Scripts tab
At the bottom of the Scripts tab pane is the familiar toolbar ribbon. You already know what the first two buttons do. After these two icons is the checkbox icon, which lets you disable the features of the Scripts tab.
Clicking on the twistie next to the object that appeared lets you see all the members of that object. Something I like about the Safari Console command line is that it has "type-ahead" intelligence. If you start to type in the name of an object that Safari can resolve, it will offer you a suggested object name that you can choose by pressing the Tab key, saving you some typing.
