 The hex editor shows the first 10 KB of a blob. Past that it reads **Truncated, read only** and refuses edits, rather than saving back the part it could show.
 
-The text box, the JSON editor and the map each carry a drag handle under them, with separate remembered heights that survive a relaunch.
+The text box, the JSON editor and the map each carry a drag handle under them. Dragging it sizes that field only. The size belongs to the column's name, so it holds on every row, in every result showing that column, and across a relaunch. A field you never dragged starts at its default height.
 
-**Open in Window** detaches a JSON, PHP, decoded binary or text value into its own resizable window; on an editable row, edits there join the same pending changes as the field. An image and a map detach read-only. The text window's status bar counts the value's characters, as the Unicode code points `CHAR_LENGTH` counts, and its bytes in UTF-8, and warns when the value holds a bidirectional control that can reorder how the text reads. The expand button on a JSON, PHP, decoded binary, long text or geometry field grows it to fill the inspector's height with the other fields still listed around it; click it again to shrink it back. Binary and image fields draw at a fixed height and carry no expand button, and neither does a geometry field stored as bytes, whose map still takes the drag handle.

 Every field carries a menu at its trailing edge, and right-clicking the field opens the same one. **Set NULL**, **Set DEFAULT**, **Set EMPTY**, **Generate UUID**, **Generate UUIDv7** and **SQL Functions** need an editable field and appear only where the column takes them, as in [Set Value](/features/change-tracking#editing-a-cell); `Ctrl+Option+N` and `Ctrl+Option+D` set NULL and DEFAULT from the keyboard. **Copy Value** is always there, and a read-only field keeps its text selectable.
