 ### Added
 
+- Sidebar search: arrow keys navigate filtered results and Enter opens the selected table, matching DataGrip behavior (#1280)
 - Right-click a column header to copy all its values from the loaded rows (#1325)
 - Copy as submenu on the row context menu now offers CSV, CSV with Headers, Markdown table, and IN Clause for SQL `WHERE id IN (...)` lookups (#1325)
 - Double-click or press Return on a read-only query result cell to open a selectable text viewer in the cell. JSON columns open the JSON viewer in a popover, BLOB columns open the hex viewer. The value is selectable and copyable (#1336)
