 - 多选与导出：Ctrl/Cmd 点击切换选择，Shift 点击选择可见范围；右键批量删除、移动或导出 Markdown。单篇无附件直接下载 `.md`，其他情况下载包含 Markdown 与本地附件的 ZIP；重名目标不会被覆盖，批量操作会汇报单项失败。
 - 设置：桌面使用居中窗口，手机使用分类与内容两级布局；支持搜索设置并定位、常用排版项单独重置，自动保存状态与失败提示可见。外观与编辑器分别管理，安装入口位于「关于」。
-- 快捷键：支持按命令名称、ID 或组合键搜索，添加、逐条移除和单项/全部重置，并拒绝冲突绑定。默认 Ctrl+Alt+1～6 设置对应级别标题，同级再次触发恢复正文；字号可直接输入，编辑器字号随有效输入即时生效。

 - 文件目录操作：右键「文件目录」标题或目录空白处，可搜索、打开标签索引、新建笔记、新建目录、导入文档及管理图片；也可点击标题打开菜单。文件夹右键操作以所选文件夹为目标。
 - 导入：文件目录或文件夹右键菜单选择「导入」，支持多选 UTF-8 `.md` 文件或单个 ZIP（总上传上限 100 MB）。ZIP 新建同名文件夹并保留笔记层级，本地图片归入各笔记同级 `assets/`；全部改链后移除已迁移且无引用的重复原图，其他附件和未使用图片保留。同名不同内容不覆盖，缺失的本地链接会提示，外部图片不会自动下载。
 - 自动化：「API 令牌」中创建只读或读写令牌，以 `Authorization: Bearer <令牌>` 调用 REST API，接口说明见 `/api/v1/openapi.json`。
