Go forward to Readline Init File.
Go backward to Introduction and Notation.
Go up to Command Line Editing.
Often during an interactive session you type in a long line of text,
only to notice that the first word on the line is misspelled. The
Readline library gives you a set of commands for manipulating the text
as you type it in, allowing you to just fix your typo, and not forcing
you to retype the majority of the line. Using these editing commands,
you move the cursor to the place that needs correction, and delete or
insert the text of the corrections. Then, when you are satisfied with
the line, you simply press <RETURN>. You do not have to be at the end
of the line to press <RETURN>; the entire line is accepted regardless
of the location of the cursor within the line.
