If you are using MarlonRichert's zsh-autocomplete plugin with oh-my-zsh on your Mac and are facing issues with the arrow keys, where the last command loaded up/down arrow keys instead of autocomplete options, then this article is for you. We will explore the key concepts of zsh, autocomplete, and oh-my-zsh, and show you how to fix this issue.
Introduction
zsh is a powerful and customizable shell for Linux and macOS platforms. Autocomplete is a feature that allows you to quickly complete commands, filenames, and variables. oh-my-zsh is a community-driven framework for managing zsh configuration.[1]
What's Causing the Issue?
The arrow key issue arises because of a conflict between the terminal's default key bindings and the zsh-autocomplete plugin.[2]
zsh-autocomplete Key Bindings
zsh-autocomplete plugin maps the arrow keys to specific functions, such as moving up and down the autocomplete suggestions. These key bindings take precedence over the terminal's default key bindings.
Terminal's Default Key Bindings
The terminal's default key bindings include the use of arrow keys for searching through the command history. When zsh-autocomplete maps the arrow keys first, it breaks the terminal's default behavior.
Solution: Override Terminal's Default Key Bindings
To solve this issue, you can disable the terminal's default key bindings for search functionality. By doing that, the zsh-autocomplete key bindings will work seamlessly.
# In your .zshrc file:
bindkey -s ^[OA 'echo -ne "\033[A"' >&1
bindkey -s ^[OB 'echo -ne "\033[B"' >&1
bindkey -s ^[OC 'echo -ne "\033[C"' >&1
bindkey -s ^[OD 'echo -ne "\033[D"' >&1
Understanding the Code
The above code snippet binds the default terminal arrow keys (^[OA, ^[OB, ^[OC, and ^[OD) with the corresponding escape sequences for up, down, right, and left arrow keys.[3]
Test the Arrow Keys
Now, reload your .zshrc file and test the arrow keys in a new terminal window.
source ~/.zshrc
