Как вызывать ф-цию, используя разные события, на жирном тексте?
The select event is sent to an element when the user makes a text selection inside it. This event is limited to <input type="text"> fields and <textarea> boxes.The keyup event is sent to an element when the user releases a key on the keyboard. It can be attached to any element, but the event is only sent to the element that has the focus. Focusable elements can vary between browsers, but form elements can always get focus so are reasonable candidates for this event type.
Так что проблема в том, что event не генерируется в принципе и тут Вы ничего не поделаете.
$('#content b').live('click', function() {  alert("Вы кликнули на жирном тексте")  });
