navigation: the list by name outside the diary, Ctrl-P goes to anything by its name, new things land beside what they belong to

The list is folders first and then by name in every space but the diary,
which stays a journal by day; a document's row elsewhere shows when it
was last edited. Ctrl-P is a jump by name across every space, served by
GET /api/jump: the last word is looked for in the name, the ones before
along the path. / is the one full-text search, and Tab on its line takes
it to every space and back. A card's notes are made in the folder being
browsed when that is in the card's space, and a missing [[link]]'s
document beside the one linking to it. o in a space with templates opens
the line as :new with them listed.

 ## Search
 
-| key | searches |
-| --- | --- |
-| `/` | the space you are in |
-| `Ctrl-P` | every space |
+`/` searches the space you are in; `Tab` on the line takes the search to every
+space, and back (`:search!` does the same from the command line).
 
 Results appear as you type, ranked by relevance, each with the space and
-folder it is in. `Tab` or `Ctrl-N` / `Ctrl-P` walk them without leaving the
+folder it is in. `Ctrl-N` / `Ctrl-P` walk them without leaving the
 line, and `Enter` opens the one lit. Afterwards `n` and `N` open the next and
 previous result beside the list, and `:noh` clears the search.
