配置在Chrome,Firefox中打开

安装 SideBarEnhancements

然后通过ctrl + k, ctrl + b打开侧边栏，在侧边栏的文件中右击，找到 open width -> edit applications

然后在这里边设置firefox打开的方式。

application : 路径要修改为自己默认安装的路径。

[
    {"id": "side-bar-files-open-with",
        "children":
        [
            //application firefox
            {
                "caption": "firefox",
                "id": "side-bar-files-open-with-firefox",

                "command": "side_bar_files_open_with",
                "args": {
                            "paths": [],
                            "application": "D:\Program Files\Mozilla Firefox\firefox.exe",
                            "extensions":".*" //any file with extension
                        }
            },

            {"caption":"-"},
            {
                "caption": "chrome",
                "id": "side-bar-files-open-with-chrome",

                "command": "side_bar_files_open_with",
                "args": {
                            "paths": [],
                            "application": "C:\Program Files\Google\Chrome\Application\chrome.exe",
                            "extensions":".*" //any file with extension
                        }
            }
        ]
    }
]

配置在IE中打开

Key bindings -> User

[
     { "keys": ["ctrl+shift+c"], "command": "copy_path" },
     { "keys": ["alt+f12"], "command": "open_in_browser" },
     { "keys": ["f12"], "command": "side_bar_files_open_with",
             "args": {
                "paths": [],
                "application": "D:\Program Files\Mozilla Firefox\firefox.exe",
                "extensions":".*" //any file with extension
            } },
    { "keys": ["ctrl+f12"], "command": "side_bar_files_open_with",
            "args": {
                "paths": [],
                "application": "C:\Program Files\Google\Chrome\Application\chrome.exe",
                "extensions":".*" //any file with extension
            } 
     }     
    
]

如果是其它浏览器，可以 ctrl+shift+c 路径，然后直接在地址栏粘贴。

这样就可以用这三个键在浏览中预览页面了：

F12 : Firefox

alt + F12 : IE

ctrl + F12 : chrome

当然，你也可以配置，其它配置器用这样的方式预览。 

在 Sublime Text 的全局配置文件 Preferences.sublime-settings 中找到 word_separators 字段，删掉其中的 - 即可双击选中一连串的多个单词。
