> A caret is just a collapsed selection.  So I would expect them to go through the same code paths.

Right. EventHandler handles both cases.

> On a desktop you move the caret with the arrow keys, but I doubt we have special handling for arrow keys + text fields, rather I suspect the arrow keys just move the selection and the selection controller causes the text area to scroll?

We don’t have a special case for arrow keys in textarea although we have a special code for editable regions (since that’s the only place where collapsed selection is rendered). FrameSelection::setSelection talks to RenderView to scroll relevant layers to "reveal" the selection.
