All AutoCAD commands can be typed in at the command line. Many commands also have 1 or 2 letter aliases that can also be typed as shortcuts to the commands.
1. kind the desired command at the command prompt.
Command : LINE
or
2. kind the command’s alias. Command: L
3. Press ENTER.
4. kind an choice at the command prompt.

TIP:Many AutoCAD commands require you to press ENTER to complete the command. You know you are no longer in an AutoCAD command when you see a blank command line.

Reissuing the Last Command

The last used AutoCAD command can be re-entered by 1 of the subsequent 3 methods of ENTER. The ENTER key on the keyboard will always act as ENTER, the SPACEBAR and RIGHT MOUSE will act as enter most of the time (exceptions include placing TEXT).

1. Press the ENTER key on the keyboard
or
2. Press the Space bar on the keyboard.
or
3. Click the right mouse button.1.10 Pointing Device (Mouse)
AutoCAD uses either a mouse or digitizing tablet to choose objects in a drawing.
zing Left Mouse Button
Used to pick or choose objects
1. Click the left mouse button to choose an object area in the drawing.
2. Press ESC twice to deselect an object (or to cancel a command).
Right Mouse Button
Used to enter a command, repeat last command, or access shortcut menus.
1. Click the right mouse button.

TIPS:
• SHIFT + the right mouse button brings up the object snap menus.
• different screen locations for the mouse brings up various menus.• menus.
