vim leader键

In Vim, the leader key is a special key that allows you to define custom key mappings. By default, the leader key is set to the backslash ("\") character. However, you can customize it to any other key of your preference.

The leader key is used in combination with other keys to create personalized shortcuts for frequently used commands or to define custom functions. For example, if you want to create a mapping to save the current file, you can use the leader key followed by another key to trigger the save command. By default, the mapping would be "\w" (leader key + "w").

To define your own leader key or modify the existing one, you can add the following line to your Vim configuration file (`~/.vimrc` or `~/.vim/vimrc`):

let mapleader = "<your-preferred-key>"

Replace `<your-preferred-key>` with the key you want to use as the leader key. After setting it, you can define your custom mappings using the leader key in your Vim configuration file or by using the `:map` or `:nmap` commands in Vim's command mode.

Using the leader key is a convenient way to create shortcuts and increase your productivity in Vim by reducing the need for lengthy and repetitive commands.
