GNU Octave
Editing What You Have Typed
At the Octave prompt, you can recall, edit, and reissue previous
commands using Emacs- or vi-style editing commands. The default
keybindings use Emacs-style commands. For example, to recall the
previous command, type Control-p (usually written C-p for
short). C-p gets its name from the fact that you type it by
holding down CTRL and then pressing p. Doing this will
normally bring back the previous line of input. C-n will bring up
the next line of input, C-b will move the cursor backward on the
line, C-f will move the cursor forward on the line, etc.
A complete description of the command line editing capability is given
in this manual in 2.4 Command Line Editing.
