bindkey is a builtin command in Zsh and tcsh shells for managing key bindings. In Zsh, it controls the Zsh Line Editor (ZLE), allowing users to map key sequences to editor widgets or macros. In tcsh, it provides similar functionality for customizing keyboard behavior.
Key bindings determine how the shell responds to keyboard input during command-line editing. By default, shells typically use Emacs-style bindings, but Vi-style bindings are also available.
To discover a key's escape sequence, press Ctrl+v followed by the key at the command line.

-e

Select Emacs key bindings (default keymap)

Select Vi key bindings, starting in insert mode

List bindings as bindkey commands suitable for .zshrc

List available keymap names

Specify keymap for binding operations (emacs, viins, vicmd)

Bind key to a string instead of a widget

Remove binding for the specified key

List bindings for prefix keys

Key sequences vary between terminal emulators. Test bindings in your specific terminal environment. Function keys and special keys like Home/End may have different escape sequences depending on the terminal.
In Zsh, bindkey operates on keymaps. The active keymap depends on the current editing mode (Emacs vs Vi). Changes to one keymap do not affect others.

The bindkey command originated in tcsh (TENEX C Shell) and was later adopted by Zsh with enhanced functionality through the Zsh Line Editor. Zsh's implementation provides more extensive customization options including multiple keymaps and user-defined widgets.
