[editing-explainer] What browser internals can be exposed to help us move the caret in (and against) the block direction? (#56)

Moving the caret within the line is not that difficult to do in JavaScript. Moving it in the block direction (or 180 degrees in the opposite direction) is much more difficult. It would help a lot if the browser could expose something about where the caret would be if it were to go one line into either direction. But what could the browser expose that would give us that?
