## `npm install` / `npm uninstall` toggle
The plugin adds a function that toggles between `npm install` and `npm uninstall` in
the current command or the last command, for up to 2 previous commands. **The default
key binding is pressing <kbd>F2</kbd> twice**.
You can change this key binding by adding the following line to your zshrc file:
```zsh
bindkey -M emacs '<seq>' npm_toggle_install_uninstall
bindkey -M vicmd '<seq>' npm_toggle_install_uninstall
bindkey -M viins '<seq>' npm_toggle_install_uninstall
```
where `<seq>` is a key sequence obtained by running `cat` and pressing the keyboard
sequence you want.
