Select commands using any of these methods:
Some commands remain active until you end them, so you can repeat an action without having to select a command repeatedly. You can end a command by clicking Done in the prompt box or by pressing Esc.
You can use most commands while another command is active. For example, while drawing a line, you may want to use the Pan command to move the drawing across the screen to select the endpoint of the line. You can also change the settings of drawing aids such as snap or grid while other commands are active.
