GDB reads its input commands via the Readline interface. This
GNU library provides consistent behavior for programs which provide a
command line interface to the user. Advantages are GNU Emacs-style
or vi-style inline editing of commands, csh-like history
substitution, and a storage and recall of command history across
debugging sessions.
You may control the behavior of command line editing in GDB with the
command set.

See Command Line Editing,

encouraged to read that chapter.
