	首先打开“终端”（Finder->应用程序->实用工具->终端），并且输入以下命令：
	defaults write com.apple.dock workspaces-edge-delay -float 0;killall Dock

	再次打开“终端”（Finder->应用程序->实用工具->终端），并且输入以下命令：
	defaults write com.apple.dock workspaces-edge-delay -float 0.15;killall Dock

	如果你想还原成原样，也很简单，再次打开“终端”（Finder->应用程序->实用工具->终端），并且输入以下命令：
	defaults delete com.apple.dock workspaces-edge-delay;killall Dock

	from contextlib import contextmanager

	@contextmanager
	def closing(thing):
	try:

	finally:
	thing.close()
	And lets you write code like this:

	// Add a div node: "id=ele_top div" as the anchor at the top of the page
	var addTop = function(){
	ele_top = document.createElement('div');
	ele_top.id = "ele_top";
	document.body.insertBefore(ele_top, document.body.firstChild);
	return true;
	};

	// Jump to the anchor node
	var toTop = function(){
