The standard shortcut for the jQuery function provided by the jQuery library is $. For instance:
$('p').css('color','red');
Would select every paragraph on the page, and change it's font color to red. This line is exactly the same as:
jQuery('p').css('color','red');
Often the $ is used by other libraries, so it may be turned off in jQuery in "noConfilct" mode.
