are there some good examples of using do!, like to focus on an element, around?

i tried

(do! :focus (.-target %) true true))

where % is a jquery event

i get Uncaught Error: Doesn't support name: [object HTMLInputElement]

ah i did

(.select (js/jQuery (str "#" (dec @i))))

(do! (str "#" (dec @i)) :select)

got it
