AutoCAD draws additional line segments.
8. Type X and then press Enter.
X isn't a valid option of the LINE command, so AutoCAD displays an error message

Point or option keyword required.
Specify next point or [Close/Undo]:
Option keyword is programmer jargon for the letter(s) shown in upper-
case that you type to activate a command option. This error message is AutoCAD's
way of saying, “I don't understand what you mean by typing X . Either specify a
point, or type a letter that I do understand.”

the next command:
Command:
10. Press F2.
AutoCAD displays the AutoCAD Text Window, which is simply an enlarged, scrol-
lable version of the command window, as shown in Figure 2-10.

need to see, but occasionally you want to review a larger chunk of command-line
history. (“What was AutoCAD trying to tell me a minute ago?!”)
11. Press F2 again.
AutoCAD closes the AutoCAD Text Window.
Figure 2-10: My, how you've grown: F2 expands the command line to a command text window.
