+## 复制粘贴画布内的节点
+
+你可以通过选中某个节点，然后按`ctrl`+`c`快捷键来复制节点，如果选中多个节点，目前只支持复制第一个节点，然后点击你要复制到的节点，按`ctrl`+`v`快捷键粘贴即可。
+
+除了快捷键，也可以通过右键菜单来操作。
+
+## 支持粘贴剪贴板中的数据
+
+当你选中某个节点后，直接按`ctrl`+`v`快捷键时，如果你的剪贴板中有数据，会粘贴你剪贴板中的数据，目前支持文本和图片两种格式，如果你的剪贴板中有图片，那么会将图片粘贴到你选中的节点里，如果存在文本，那么会以该文件创建一个子节点。
+
+如果你的剪贴板中存在数据，又在画布里复制了节点数据，那么是以谁最后改变了为准。
+
+## 支持跨浏览器标签、跨浏览器复制
+
+如果你在多个浏览器里打开了思维导图编辑页面，那么可以复制一个页面的节点数据到另一个页面进行粘贴。
+
+在客户端场景下打开了多个编辑页面时比较常用。
