We are talking about keyboard focus. It was decided that keyboard navigation is important for accessibility, that is why we focus on the first control element of the active dialog. 

Can you explain more why we focus on the first control element of the active dialog for keyboard navigation? Most of the users do not need to switch to other languages, and they can go to the left for the additional options. 

We've gone back and forth on this in other bugs. 

In https://bugs.chromium.org/p/chromium/issues/detail?id=696898 we decided to focus on "Let's go!", but in https://bugs.chromium.org/p/chromium/issues/detail?id=707939 we said focus on the first element and maybe look into not having visible focus. 

My reaction is to having the visible focus on the first screen. I think it over-emphasizes a secondary action which decreases the visual clarity of the page. Is there a middle ground here where we can keep the focus on the first UI element but have it be invisible? Or is that not feasible? 

zalcorn@ what do you think?

Regular users will not usually use keyboard for navigation. Keyboard navivation is mostly used for accessible navigation. So "Tab" should reasonably navigate thouth the page. Per https://bugs.chromium.org/p/chromium/issues/detail?id=707939#c6 we focus on the first control element in the dialog.

In the old OOBE, Tab navigation was explicitly set to "OK" -> "Language selection" -> "keybord selection" -> "Network selection". Which did not match the order of UI elements either.
