+| `clickElement(text, {dblclick?})` | Click button/link/tab (fuzzy). `{dblclick:true}` to open items from lists. If returns `submenu[]` — click again with item name |
 | `fillFields({name: value})` | Fill form fields (fuzzy by name or label). Auto-detects checkboxes, radio, reference fields |
 | `selectValue(field, search)` | Select from reference field via dropdown/selection form |
 | `fillTableRow(fields, opts)` | Fill table row cells via Tab navigation. See below |
 | `deleteTableRow(row, {tab?})` | Delete row by 0-based index |
+| `closeForm()` | Close current form/dialog via Escape. Returns confirmation if unsaved changes |
 | `filterList(text, opts)` | Filter list. Simple (text only) or advanced (text + field). See below |

+### Open item from list
+
+```js
+// Double-click to open a document/catalog item from a list
+await clickElement('0000-000227', { dblclick: true });
+// Returns the opened form state (fields, table, buttons)
+```
+
+Single `clickElement(text)` only selects the row. To open — always use `{dblclick: true}`.
+
+### Hierarchical lists (catalogs)
+
+Simple search (`filterList('text')`) does NOT work for hierarchical catalogs — it shows
+groups instead of filtering elements. For Контрагенты, Номенклатура, Сотрудники, etc.
+always use advanced search with a specific field:
+
+```js
+await filterList('Конфетпром', { field: 'Наименование' });  // correct
+// NOT: await filterList('Конфетпром')  -- shows groups, not flat results
+```
+
+Hint: if `readTable()` returns rows with `_kind: 'group'`, the list is hierarchical.
+
+### Closing forms
+
+| Action | Method |
+|--------|--------|
+| Post & close document | `clickElement('Провести и закрыть')` |
+| Save & close catalog | `clickElement('Записать и закрыть')` |
+| Close without saving | `closeForm()` (Escape) or `clickElement('Закрыть')` |
+| Confirmation dialog | Response has `confirmation` field — call `clickElement('Да'/'Нет')` |
+
+`closeForm()` is preferred over `clickElement('×')` — close buttons on tabs are ambiguous.
