Display Valid Commands and System Variables
By default, AutoCAD LT automatically completes the name of a command or
system variable as you type it. Additionally, a list of valid choices is displayed
from which you can choose. Use the AUTOCOMPLETE command to control
which automatic features that you want to use.
If the automatic completion feature turned off, you can type a letter on the
command line and press TAB to cycle through all the commands and system
variables that begin with that letter. Press Enter or Spacebar to start the
command or system variable.
Enter Alternate Names of Commands
Some commands also have alternate names. For example, instead of entering
line to start the LINE command, you can enter l. Alternate command names
are called command aliases and are defined in the acadlt.pgp file.
To define your own command aliases, see Create Command Aliases in the
Customization Guide.
Specify Command Options
When you enter commands on the command line, you see either a set of
options or a dialog box. For example, when you enter circle at the Command
prompt, the following prompt is displayed:
Specify center point for circle or [3P/2P/Ttr (tan, tan, radius)]:
You can specify the center point either by entering X,Y coordinate values, or
by using the pointing device to click a location in the drawing area.
To choose a different option, enter the letters capitalized in one of the options
in the brackets. You can enter uppercase or lowercase letters. For example, to
choose the three-point option (3P), enter 3p.
Execute Commands
To execute commands, press Spacebar or Enter, or right-click your pointing
device after entering command names or responses to prompts. The
instructions in Help assume this step and do not specifically instruct you to
press Enter after each entry.
Repeat and Cancel Commands
If you want to repeat a command that you have just used, press Enter or
Spacebar, or right-click your pointing device at the Command prompt.
