How to take screenshots for UI element?

[birdywen]

for (var e = w.Elm["web:LINK", "* Brand Logo"].Find(); e != null; e = e.Navigate("pa3 ne ch3 fi2")) {
    e.Focus();
     keys.send("Apps");

Hi Gintaras, I really can't figure out how this line of code can implement the entire for loop,could you please tell me how this code works? Also, I don't see you using e.scroll to(), but the code still focuses on the element, what's the reason for that? 

Thank you for the explanation!
