You can display commands, system variables, options, messages, and prompts in a dockable and resizable window called the command window.
You can enter a command by using the keyboard. Some commands also have abbreviated names called command aliases.
System variables are settings that control how certain commands work.
You can edit text in the command window to correct or repeat commands.
You can display prompts on the command line instead of using a dialog box, or switch back again. This option is useful primarily when using scripts.
Change the position and display of the command window to suit the way you work.
