To make working with commands easier, AutoCAD and AutoCAD LT offer shortcuts for repeating and canceling commands as well as sophisticated undo and redo options. You can also use certain commands in the middle of another command.
You can have more than one command in process concurrently, one in each open drawing. You can switch from one open drawing to another without interrupting your commands. For example, if you’re in the middle
of drawing a circle in one drawing, you can open a new drawing and start another command to get some information you need for the circle. Then you can return to the first drawing and complete the circle.
Repeating commands
The most common way to repeat a command you have just used is to press Enter. The most recent command appears again.
TIP, You can also press the Spacebar at the Command: prompt to repeat a command you just used. This technique works well if you want to keep one hand on the mouse and use the other hand to press the Spacebar.
If you know in advance that you’ll be using a command several times, you can use another technique —
type multiple ↵. At the Enter command name to repeat: prompt, type the command name on the command line. The command automatically reappears on the command line. For example, you could type multiple and then arc if you knew you were going to draw several arcs in a row. To stop repeating the command, press Esc.
TIP, If you create a ribbon or toolbar button that executes a customized set of actions (as I explain in Chapters 29 and 33), right-click and choose the top option of the shortcut menu to repeat the action of the custom button. You cannot press Enter to get this effect.

  • The shortcut menu is context-sensitive. When you right-click in the graphics window, you can use the
    options presented on the shortcut menu to perform a variety of tasks. Context-sensitive means that
    the menu will change depending on what you are currently doing in the software. For example, if you
    are at the Command prompt your shortcut menu will have different options available than if you are
    in the Pline command.
    Definition of Shortcut Menu
    Shortcut menu options are organized into different areas. The options that are made available to you
    are based on the current context of your work and will change when you activate the shortcut menu.
    The following image shows the shortcut menu as it appears when you are creating a polyline.
    The top area of the menu offers
    Enter, Cancel, and Recent Input
    options.
    The middle area of the menu offers
    options specific to the current
    command. Notice how the options
    on the menu match the options
    on the command line. To use an
    option for a command, select the
    option on the shortcut menu. This
    has the same effect as typing the
    capital letter(s) of the option on
    the command line.
    The lower area of the menu offers
    Pan and Zoom functions and access
    to the QuickCalc command.

    Key Points
    n The shortcut menu is context-sensitive, so its options differ depending on the current context of
    the software, for example, whether you are drawing or editing.
    n You can use the shortcut menu as an alternative to entering command options on the command
    line. This speeds up the design process and is the preferred method for working with sub-options
    of the active command.
