2. dash和alfred结合
安装完dash和alfred后，在dash的设置页面的Integration选项卡点Alfred，这时Alfred会自动安装dash的workflows，安装后就可以直接用了，语法为`dash 语言:关键字`
Open Alfred and type "dash" followed by your query to initiate a Dash search from Alfred.
This also works with docset keywords (defined in Preferences > Docsets) or search profile keyword triggers (defined by clicking on the loupe icon of the main search field).
Keyword example: "php printf".
