Every current major browser provides an API to create a range from a mouse event, although there are four different code branches needed.

• Creating a collapsed range from a pixel position in FF/Webkit

Here's a demo: http://jsfiddle.net/timdown/krtTD/10/

And here's some code:

function getMouseEventCaretRange(evt) {
    var range, x = evt.clientX, y = evt.clientY;

    // Try the simple IE way first
    if (document.body.createTextRange) {
        range = document.body.createTextRange();
        range.moveToPoint(x, y);
    }

    else if (typeof document.createRange != "undefined") {
        // Try Mozilla's rangeOffset and rangeParent properties,
        // which are exactly what we want
        if (typeof evt.rangeParent != "undefined") {
            range = document.createRange();
            range.setStart(evt.rangeParent, evt.rangeOffset);
            range.collapse(true);
        }

        // Try the standards-based way next
        else if (document.caretPositionFromPoint) {
            var pos = document.caretPositionFromPoint(x, y);
            range = document.createRange();
            range.setStart(pos.offsetNode, pos.offset);
            range.collapse(true);
        }

        // Next, the WebKit way
        else if (document.caretRangeFromPoint) {
            range = document.caretRangeFromPoint(x, y);
        }
    }

    return range;
}

function selectRange(range) {
    if (range) {
        if (typeof range.select != "undefined") {
            range.select();
        } else if (typeof window.getSelection != "undefined") {
            var sel = window.getSelection();
            sel.removeAllRanges();
            sel.addRange(range);
        }
    }
}

document.getElementById("editor").ondblclick = function(evt) {
    evt = evt || window.event;
    this.contentEditable = true;
    this.focus();
    var caretRange = getMouseEventCaretRange(evt);

    // Set a timer to allow the selection to happen and the dust settle first
    window.setTimeout(function() {
        selectRange(caretRange);
    }, 10);
    return false;
};

$('p').dblclick(function(event) {
  $this = $(this);
  $this.attr('contenteditable', "true");
  $this.blur();
  $this.focus();
});
