# Reference The Selected Node In the Chrome dev tools, if you've selected (highlighted) a node in the DOM, you can reference that node from the console with `$0`. This is handy if you are debugging or exploring certain parts of a page and need to run commands against that node. For instance, if you were to select the `` node in the DOM, you could then programmatically check the `lang` attribute from the console like so: ``` > $0.lang // "en-US" ``` If there is `jQuery` on the page and you've selected the node that contains all of the page's content, you can do something like the following: ``` > $($0).html('

Hello, World!

') ```
