Interaction · Keys, scroll and focus: roving focus, scroll sync, type-ahead

RovingFocus keeps a row or column of items behind one Tab stop: the
arrows walk focus, Home and End reach the ends, Enter or Space presses,
and a press moves the stop without taking focus. ScrollSync keeps boxes
at one place along an axis: the pane a wheel turned leads, and a canvas
ahead of the panes copies its place before they draw. SelectableList
moves its cursor to the row that starts with the letters typed, the
letters joining within a pause and a Command letter left to the app.
forms::History becomes public as the undo manager. The gallery shows
gpui's own key bindings, a two-stroke chord waiting on its first
stroke, uniform_list, autofocus and the focus ring.
