Lazyvim 自带的快捷键有时候不符合我的心意，直接绑定新的快捷键不一定会达到你想要 的效果，下面是我总结的如果disable默认快捷键的方法

粗暴方法​

我会直接在绑定新的快捷键之前，删掉对应的已有的快捷键，但是这种方法并不总是有效

vim.keymap.del("n", "<leader>l", {})

Lsp 相关的快捷键​

因为我想要把 gd 绑定到 Lspsaga 提供的功能上，所以需要先 Disable 掉 Lazyvim 自带的绑定

https://www.lazyvim.org/plugins/lsp#%EF%B8%8F-customizing-lsp-keymaps

这里可以理解为在 keys 这个自带的 array 里面 append 了一个 ele，这个 ele 会 disable 掉前面默认定义的快捷键

  {
    "neovim/nvim-lspconfig",
    init = function()
      local keys = require("lazyvim.plugins.lsp.keymaps").get()
      -- disable a keymap
      keys[#keys + 1] = { "gd", false }
    end,
  },

其他插件默认的快捷键​

以 Flash 为例, 我需要把 S 在 visual 模式下作为 surround 插件的快捷键，但是Flash 现在会使用这个快捷键，所以需要先 Disable 掉它

keys = {
    ...
    { "S", false, mode = { "v" } }, -- https://github.com/folke/flash.nvim/discussions/251
  }
}

  1. [] 方括号索引器:

    • 通常用于根据列标签选择列。
    • 也可以用于选择行，但这通常是通过传递一个布尔序列或布尔条件来实现的，而不是直接通过行标签。

    示例：

    df['column_name']  # 选择名为 'column_name' 的列
    df[['column1', 'column2']]  # 选择 'column1' 和 'column2' 这两列
    df[df['column'] > 10]  # 根据布尔条件选择行

  2. .loc[] 方法:

    • 基于标签进行索引。
    • 可以用于同时选择行和列。
    • 行标签和列标签都需要明确指定。

    示例：

    df.loc[5, 'column_name']  # 选择索引标签为 5 的行和名为 'column_name' 的列的单个值
    df.loc[0:5, 'column_name']  # 选择索引标签从 0 到 5 的行和 'column_name' 列
    df.loc[:, 'column_name']  # 选择所有行的 'column_name' 列

  3. .iloc[] 方法:

    • 基于位置进行索引。
    • 也可用于同时选择行和列。
    • 使用整数索引来指定行和列的位置。

    示例：

    df.iloc[5, 2]  # 选择第 6 行和第 3 列的单个值
    df.iloc[0:5, 2]  # 选择第 1 到第 5 行和第 3 列
    df.iloc[:, 2]  # 选择所有行的第 3 列

总结：[] 方括号索引器主要用于选择列，而 .loc[] 和 .iloc[] 方法则可以用于根据行标签或列标签（.loc[]）或根据行列的位置（.iloc[]）来选择行和列。
