How to exit a code block?（如何结束代码块）

[wmbstx]

It seems that in editor, a code block cannot be ended simply by typing ```. You can only use the arrow keys to jump out of the code block. But if you happen to have two code blocks adjacent to each other and you want to insert some text between them, what options can I have?

代码块好像不能用```来结束？只能使用上下键来跳出代码块，如果碰巧遇到两个代码块相邻，而你又想在两个代码块之间补一段话的话，有什么可用的办法吗？
