Readline Interaction
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 use Return. You do not have to be at the end of the line to use Return; the entire line is accepted regardless of the location of the cursor within
the line.
