=== 使用教程 ===
**功能简介**：
洛谷反诈中心脚本用于检测并提示洛谷网站中的疑似诈骗链接。用户可以自定义两种模式的关键词列表：
1. **匹配关键字模式**：使用简单的字符串进行匹配。
2. **高级模式**：使用正则表达式进行匹配。
**关键词配置**：
1. **打开编辑界面**：在洛谷页面，按下 `Ctrl + M` 快捷键将打开关键词编辑界面。
2. **编辑关键词**：
- **匹配关键字模式**：
- 每个关键词以独立的块展示，块与块之间有清晰的分割线。
- 点击 `🖊` 按钮可直接在原位编辑关键词。
- 点击 `×` 按钮可删除关键词。
- 点击 `+ 添加关键词` 按钮可添加新的关键词。
- **高级模式（正则表达式）**：
- 每个正则表达式以独立的块展示，块与块之间有清晰的分割线。
- 点击 `🖊` 按钮可直接在原位编辑正则表达式。
- 点击 `×` 按钮可删除正则表达式。
- 点击 `+ 添加正则表达式` 按钮可添加新的正则表达式。
- 正则表达式需用斜杠 `/` 包裹，例如：`/^https?:\/\/(www\.)?example\.com/`
3. **保存设置**：编辑完成后，点击 `保存` 按钮，新的关键词和正则表达式列表将被保存并立即生效。
**使用说明**：
- 当鼠标悬停在包含疑似诈骗关键词或符合正则表达式的链接上时，将显示一个提示框。
- 点击该链接时，将在鼠标旁边弹出确认窗口，显示链接地址。
- 您可以通过以下方式操作：
- 点击 `确定 (Enter)` 或按下 `Enter` 键以确认打开链接。
- 点击 `取消 (Esc)` 或按下 `Esc` 键以取消操作。
**注意事项**：
- 请确保正则表达式的语法正确，否则可能导致匹配不准确。
- 关键词列表支持动态修改，您可以根据需要随时更新。
