Unlike other key events in javascript, keypress may capture the actual character, that would be inserted in text field (only applies on editable elements, like text fields and content-editable html elements). This is hidint under event.charCode. On other events, such as keyup and keydown you only may capture ID of the key - with different systems, and languages, the same number may mean totally different characters.
On the other side, keypress along with keyup may not block many default event actions - like pressing tab, F5 or arrows.
