j/n and k/p step through the items, Shift-J and Shift-K through the feed
list, and g with a letter goes to a place: All Subscriptions, Directory,
Popular, Currently Listening, Settings. o plays the selected item, m marks
it read or unread and s keeps it, each by pressing the toolbar's own
button; v opens the original, Shift-A marks all read, r refreshes, [ hides
the feed list, and ? lists them all. None fire while typing, with a
modifier held, or with a dialog open.
Closes#8.
