Command Techniques

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.
