Jump to top/bottom in context menus

Although we don't have any context menu options which start with the
letter G yet, if we did, the keyboard selector would (intentionally)
take priority and focus that element instead of doing jump to start/
bottom behavior. However, pressing Home/End will always work (once it's
implemented).
