In-line editing provides the ability to edit the current or previous commands before executing them. There are three in-line editing modes available: emacs, gmacs, and vi. The emacs and gmacs modes are basically the same, except for the way Ctl-t is handled. The inline editing mode is specified by setting the EDITOR or VISUAL variables, or with the set o command. The editing window width is specified by the COLUMNS variable. For lines longer than the window width, a mark is displayed to notify position. The marks >, <, and * specify that the line extends to the right, left, or both sides of the window.
