Chrome Dev Tools Selection Variable
Highlight a few HTML elements in the Chrome Developer Tools Elements inspector, and you'll have a traversable history. The selected element is stored in a variable called $0. We can manipulate it like so:
> $0.click();
Try this when the selected element is hidden or difficult to click. There are four more variables representing your most recently selected elements: $1, $2, $3, and $4.
