The prompt line, located at the bottom of the window under the status line, provides ongoing feedback, based on the current cursor position and the current program activity. When you don’t know what to do next, look down here for instructions.

If you don't want to take the time to save the auto backup file, you can press the Esc key to stop the auto backup. (The "Autobackup in progress" message is usually brief: It lingers on the screen only when saving very large files, and these are the occasions where you might want to stop the auto backup in order to continue working.)
