• Use Library. Add a library to the list of libraries in use on this schematic.

• Execute a Script. See Chapter 10.

• Execute a User-Language Program. See Chapter 10.
• Zoom to Fit. Zooms to just fit all the components in the schematic into the editor area (useful).

• Zoom In. It is easier to use the scroll wheel on your mouse if you have one.

• Zoom Out.

• Redraw Screen. Occasionally, screen redraw is glitchy. This forces a redraw of the screen.

• Zoom to Selection.

• Undo. Undo the last change made to the schematic (very useful).
• Redo.

• Cancel Command. Cancel a command that is running.

• Help. Search for help about using EAGLE.

Under the Action toolbar, you will find the Parameter toolbar. The contents of this toolbar will
change as you select different commands in the Command toolbar. It is the Command toolbar that you

will use most when you are editing a schematic. We will deal with this specifically in the next
section.
Underneath the Parameter toolbar is a gray area that displays the current coordinates of the cursor.

To the right of this is a text entry field called the command line, where you can type commands
equivalent to pressing buttons. We will look at this briefly in Chapter 9 because generally users
prefer to click on commands rather than type them.

The Command Toolbar

The icons in the Command toolbar are labeled in Figure 4-2. There are a lot of commands that we can
use. The ones labeled in bold in the figure are the most commonly used ones. You will use these
commands a lot. Some of the others deserve a mention so that you know they are there when you do

come to need them.
