Remarks
There are several things that cause a command to be terminated. When a command finishes it will terminate. For example when you execute the Extrude command, after the extrusion has finished the command terminates. Starting another command while one command is active will cause the active command to terminate. An exception to this is the viewing commands. They just temporarily suspend the active command rather than terminate it. Pressing the escape key will terminate the current command.
