When using the console on a Javascript-free page I noticed that when typing $ had the same effect as document.querySelector and while typing $$ had the same effect as document.querySelectorAll.
Would be two shortcut functions for querySelector or they have some different specific behavior?
What are their names? I even looked in the kennel http://caniuse.com/#search=%24%24, but I didn’t get any results (I tried "dollar" as well)

These are console-only methods, shortcuts to facilitate the programmer.
This is confirmed in chrome documentation here and in the Edge documentation here where it says:
$() is a shortcut to Document.querySelector().
$$() is a shortcut to Document.querySelectorAll().
$0, $1, $2, $3, $4 returns the last elements selected by the DOM explorer (Elements)
There is still the $_ but this has a different behavior in Chrome and Edge:
Edge:
$_() is a shortcut to last object/element.
Chrome:
$_ is a shortcut to show the value of the last evaluated expression.

These are methods that come with the console.

I also think it’s good to have the question on the site. I just don’t have time to research to put a decent answer now, so the first comment.
