修改Vim快捷键：Bepo键盘下替换hjkl为ctsr的方法

Hey there! Since you’re using a Bépo keyboard layout and want to swap the classic hjkl cursor movement keys with ctsr, the exact setup depends on which editor you’re using. Let’s break down the most common cases to get you sorted:

Vim is the most common tool where hjkl is deeply ingrained, so this is probably what you’re asking about. Here’s how to set it up:

• Open your Vim configuration file: ~/.vimrc for Vim, or ~/.config/nvim/init.vim for Neovim.
• Add these lines to remap the cursor movement keys:

  " Map ctsr to left/down/up/right in normal mode
  nnoremap c h
  nnoremap t j
  nnoremap s k
  nnoremap r l
  
  " Optional: Insert mode movement (use Ctrl combinations to avoid input conflicts)
  inoremap <C-c> <Left>
  inoremap <C-t> <Down>
  inoremap <C-s> <Up>
  inoremap <C-r> <Right>
  

  The nnoremap command creates non-recursive mappings, which means you won’t run into unexpected conflicts with existing shortcuts. For insert mode, using Ctrl+key combinations ensures you don’t overwrite the ability to type regular c/t/s/r characters.

If you’re using VS Code (with or without the Vim extension), here’s how to adjust your keybindings:

• Open the settings panel with Ctrl+, (Windows/Linux) or Cmd+, (Mac).
• Search for "Keyboard Shortcuts" and click "Open Keyboard Shortcuts (JSON)".
• Paste this configuration into the keybindings.json file:

  [
      // Normal mode (for VS Code Vim extension users)
      {
          "key": "c",
          "command": "vim.left",
          "when": "editorTextFocus && vim.mode == 'Normal'"
      },
      {
          "key": "t",
          "command": "vim.down",
          "when": "editorTextFocus && vim.mode == 'Normal'"
      },
      {
          "key": "s",
          "command": "vim.up",
          "when": "editorTextFocus && vim.mode == 'Normal'"
      },
      {
          "key": "r",
          "command": "vim.right",
          "when": "editorTextFocus && vim.mode == 'Normal'"
      },
      // Optional: Insert mode movement
      {
          "key": "ctrl+c",
          "command": "cursorLeft",
          "when": "editorTextFocus && vim.mode == 'Insert'"
      },
      {
          "key": "ctrl+t",
          "command": "cursorDown",
          "when": "editorTextFocus && vim.mode == 'Insert'"
      },
      {
          "key": "ctrl+s",
          "command": "cursorUp",
          "when": "editorTextFocus && vim.mode == 'Insert'"
      },
      {
          "key": "ctrl+r",
          "command": "cursorRight",
          "when": "editorTextFocus && vim.mode == 'Insert'"
      },
      // Optional: Unbind original hjkl keys to prevent conflicts
      {
          "key": "h",
          "command": "-vim.left",
          "when": "editorTextFocus && vim.mode == 'Normal'"
      },
      {
          "key": "j",
          "command": "-vim.down",
          "when": "editorTextFocus && vim.mode == 'Normal'"
      },
      {
          "key": "k",
          "command": "-vim.up",
          "when": "editorTextFocus && vim.mode == 'Normal'"
      },
      {
          "key": "l",
          "command": "-vim.right",
          "when": "editorTextFocus && vim.mode == 'Normal'"
      }
  ]
  

  If you don’t use the Vim extension, just replace the vim.left/vim.down commands with cursorLeft/cursorDown and adjust the when condition to editorTextFocus && !editorReadonly.

For tools like Sublime Text, Emacs, or any other editor with customizable shortcuts, the core idea is the same:

• Open the editor’s keyboard shortcut settings menu.
• Locate the "cursor left", "cursor down", "cursor up", "cursor right" commands.
• Bind each command to the corresponding c/t/s/r key (or use Ctrl combinations if you need to preserve the original key’s function for typing).
