bindkey -r - Delete the binding mapped to the keystroke.

bindkey - Output the widgets bound to a specific keystroke in the global keymap.

bindkey - Output all the key bindings for the global keymap.First, let’s see how we can display what was already bound by using: To manage our custom keystrokes, we need to use the bindkey command. How do we bind custom keystrokes to these Zsh widgets? Managing the Bindings That’s nice to have many keymaps to choose from, but it’s not enough.

To understand how ZLE works, we first need to understand the concept of keymap.Ī keymap is a set of keystrokes executing ZLE widgets. We’ve already seen some of the ZLE built-in widgets in the first part of this series of article, like vi-backward for example. Like “scalable”, and of course “ daffodil”. That’s great, because the term “command” is so overloaded that it doesn’t mean anything anymore. It also allows you to use keystrokes to execute ZLE commands, more commonly called widgets. It’s your interface to the shell interpreter, allowing you to write and edit your mind-blowing commands. The Zsh Line Editor (ZLE) is simply your command prompt.
