We can break both a $(selector).each() loop and a $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.
return false; // this is equivalent of 'break' for jQuery loop
return; // this is equivalent of 'continue' for jQuery loop
Note that $(selector).each() and $.each() are different functions.

Although true, this doesn't seem to be documented. Is this an 'unofficial' feature?

It is documented here api.jquery.com/jquery.each @MichaelScheper

That's the first place I looked, of course. I see it now; it kinda gets lost amongst all the examples.

return true; is also equivalent to continue.
$('.submit').filter(':checked').each(function() {
//This is same as 'continue'
if(something){
return true;
}
//This is same as 'break'
if(something){
return false;
}
});

return or return false are not the same as continue. If the loop is inside a function the remainder of the function will not execute as you would expect with a true "continue".
