Sublime-text3如何设置浏览器

Preferences -> Key Bindings 进入设置快捷键的页面，输入以下代码

     //默认浏览器
	{"keys": ["f1"], "command": "open_in_browser"},

	//Chrome
	{"keys": ["f2"], 
	"command": "side_bar_files_open_with", 
	"args": {
		"paths": [],
		"application": "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe",
		"extensions": ".*"
		}
	},
	
	//QQ浏览器
	{
		"keys": ["f3"],
		"command": "side_bar_files_open_with",
		"args": {
			"paths": [],
			"application": "D:\\Heather_install\\QQBrowser\\QQBrowser.exe",
			"extensions": ".*"
		}
		
	}

为不同的浏览器设置不同的快捷键，之后使用快捷键皆可以运行html代码。
