Comment(by azaozz):

 These two do the same thing:
 {{{
 $('.wp-menu-toggle', menu)...
 }}}

 {{{
 menu.find('.wp-menu-toggle')...
 }}}

 They limit the search for the `.wp-menu-toggle` class only to children of
 `menu`. Did some testing few months ago and the first one was slightly
 faster.

 It can also be written as:
 {{{
 $('li.wp-has-submenu', '#adminmenu')...
 }}}
 i.e. find `li` nodes that have `wp-has-submenu` class but search only in
 the node with id = `adminmenu`.
