Clicking a comment balloon in the markup area selects it like Word: its text becomes editable in place, with Reply, Resolve/Reopen and Delete, and replies are shown (and editable) under the comment they answer. Each edit is written back through a new review.editComment command, one undo step per editing session; the Comments pane uses the same path (it used to write the text without an undo step) and gains a Reply button. The margin edges on the horizontal ruler (left/right) and the vertical ruler (top/bottom) can be dragged to set the section's margins through layout.margins, one undo step per drag, snapped to 1/16 inch and clamped so at least an inch of text remains. Indent markers keep priority where they overlap an edge. Setting margins by number no longer switches off mirrored margins; only a preset decides that.

Control protocol
Start the app with a control port: wordcraft --control 7981 (or WORDCRAFT_CONTROL_PORT=7981).
It listens on 127.0.0.1 only. Send one JSON object per line, with the window's key (see
Keys); each gets one reply line:
{"id": 1, "key": "…", "method": "engine.execute", "params": {"command": "text.insert", "params": {"text": "Hello"}}}
{"id": 1, "ok": true, "result": {"anchor": {...}, "focus": {...}}}
Errors come back as {"id": …, "ok": false, "error": "message"}. A failed command leaves the
document unchanged. A line that isn't valid JSON gets one error reply, then the server closes the
connection (so an HTTP request sent to the port can't run a command); reconnect to continue.
Keys
Any local program (and possibly a web page) can reach a loopback port, so every request needs the
window's key. Once the port is bound, the app writes a random key (256 bits, as hex) to
<settings>/control-key.<instance> and removes the file when the window closes; a new start
writes a new key. <settings> is the folder that holds the preferences: on Linux
$XDG_CONFIG_HOME/wordcraft (by default ~/.config/wordcraft), on macOS
~/Library/Application Support/WordCraft, on Windows %APPDATA%\WordCraft. <instance> is the
Flatpak instance id inside Flatpak, and local-<port> otherwise. On Unix the file has mode 0600.
cat ~/.config/wordcraft/control-key.local-7981 # Linux, outside Flatpak, port 7981
- Send the key as top-level
"key"with every request, or once per connection with{"method": "auth", "key": "…"}(reply{"ok": true, "result": {}}); later requests on that connection may leavekeyout. Onlyauthreadsparams.key; for other methodsparams.keyis an ordinary parameter (ui.key {"key": "Enter"}presses Enter). - The key is checked on every request. A missing or wrong key gets
{"ok": false, "error": "unauthorized"}, and the app closes the connection. - A line over 1 MiB gets
{"ok": false, "error": "line too long"}, and the app closes the connection. - A connection that sends no authorised request within 30 s of being accepted is closed. That is one limit: blank lines and bad JSON do not extend it. After an authorised request the connection may stay idle.
wordcraft-cli mcp --connect takes the key from WORDCRAFT_CONTROL_KEY, or else from the key
file for the port it connects to, and reads it again on every new connection (the app may have
restarted). It sends the key only to loopback addresses (127.0.0.0/8, ::1, localhost). For
any other host it sends no key, says so, and the app refuses its requests: to drive an app on
another machine, forward its port to 127.0.0.1 (for example ssh -L 7981:127.0.0.1:7981 host)
and set WORDCRAFT_CONTROL_KEY to that app's key.
