What does this mysterious selector do?
What's the difference between
$.fn.insertAtCaret = function (myValue) // i saw this in an example, but don't know what it means
and
function insertAtCaret (myValue) // this doesn't work in his example but is similar to how I name functions
I checked the jquery documentation for selectors but his selector isn't covered, so I don't know how he came up with it.
It seems somewhat similar to jQuery.fn.extend() but he's not using .extend
