使用sublime时由于经常要在ie chrome firefox等浏览器中预览，所以很有必要设置多个浏览器预览

步骤：

（1）安装SideBarEnhancements插件（用sublime的应该都知道）

（2）安装好以后点击工具栏的     preferences > package setting > side bar > Key Building-User键入以下代码

（3）说明: 注意自己浏览器的安装位置就ok了

例如:

{ "keys": ["f3"],            "command": "side_bar_open_in_browser" ,            "args":{
    "paths":[], "type":"testing", "browser":"safari"}    },            { "keys": ["f4"],        "command": "side_bar_open_in_browser",        "args":{
    "paths":[], "type":"production", "browser":"chrome"}    },    {        "keys": ["ctrl+t"],        "command": "side_bar_new_file2"    },    {        "keys": ["f2"],        "command": "side_bar_rename"    },

 以下测试可用

[{ "keys": ["f3"],            "command": "side_bar_open_in_browser" ,            "args":{
    "paths":[], "type":"testing", "browser":"safari"}    },            { "keys": ["f1"],        "command": "side_bar_open_in_browser",        "args":{
    "paths":[], "type":"testing", "browser":"chrome"}    },        { "keys": ["f2"],        "command": "side_bar_open_in_browser",        "args":{
    "paths":[], "type":"testing", "browser":"firefox"}    },]
