Unified key bindings roughly to
localleader=, anything with `,` in front will affect the current
documents somehow (e.g. mark them read, add a tag, ..).
jumpto=' prepending with `'` will affect the current view
(e.g. limit to unread documents, limit to entries with notes, ..).
Sorting can be done with `S`, like in vifm.
Display style can be toggled to table with `T`.
