On loading a new page, focus the longest scrollable element

[venteto]

Keyboard navigation doesn't seem to work intuitively ... I routinely find myself not at the top of whatever new page loads, then I hit the Home or Page Up keys on my keyboard, and nothing happens.Sometimes I can start adding a step of trying to click somewhere in the middle, main content column, which then seems to make by keyboard work as expected ... but then if I had to click anything for my keyboard to work, I haven't gained much over having to click the little JavaScripty arrow element at the bottom left of the middle column. So in this case it doesn't seem like relying on JavaScript for a UI broke the interface, but just the wrong element of the page is being given focus on load?
