Backing out of jams

Sometimes, especially as a beginner, you might open some item and then not know what to do with it.
In this case, you’ll probably want to back out of that selection until you get to more familiar territory.
When you find yourself in unfamiliar territory, try any of these techniques to back out of your current
situation gracefully:
Click somewhere on the desktop, or some other neutral looking area of the screen. Doing
so will often undo whatever your last click did.
Press the Escape key (labeled Esc or Cancel) on the keyboard. This key is so named
because it enables you to escape from unfamiliar territory. And it’s a darn good key to
become familiar with.
Look for any of the buttons shown in Figure 1-8. If you see one, click it. You’ll be taken back
to wherever you were before without a hitch.
