dashboard: the document box edited from its menus alone

With the entries' menus (1238), editing had three ways in: the
double-click, the `+` on a map's or list's row, and the menu. The
double-click and the `+` go; the menu does all of it. The title,
which stands for the root (its row isn't shown), now takes the
right-click too: its menu adds a key at the top level.

 ## Document
 
 The swarm's document, as this node holds it: its keys listed at the top level, how
-many beside the title, with the `+` that adds one. A branch is read
+many beside the title. A branch is read
 when opened, and read again when the document changes there; what changed or came
 breathes once, as the map's labels do: its row glows and fades.
 
 Editing writes to the document, as the user the page was opened as, and the write goes
 to the whole swarm like any other:
 
-* **Double-click an entry** to edit it: a string as text, anything else as JSON, a map
-  or list whole. Saved, it is shown open. The red `Delete` beside `Save` deletes the
-  entry instead, on a second click (`Delete: sure?`) from half a second to 3 s later: a
-  double-click doesn't delete.
-* **`+` on a map's row** adds a key and its value (beside the title: a key at the top
-  level).
-* **`+` on a list's row** inserts an item at an index (`-1`: at the end); the items
-  from there on move up.
-* **Right-click an entry** (or hold a finger on it) for its menu: `Edit value` (as the
-  double-click), `Rename key` (a map's key), and on a map `Add a key`, on a list
-  `Append an item` or `Insert an item at…` (as the `+`, the index asked for). Renaming
-  reads the value, writes it under the new key and deletes the old one: two writes, the
-  value as JSON, as the store reads it; a key that exists already isn't overwritten.

 Each user sees and edits what its capabilities let it ([`access.md`](access.md)): of a part it
 may only partly read, the keys on the way to what it may. Protocol data (`_continuum`)
