In Development mode, copy and paste work by default.

However, in Application mode, these actions may not work if the Edit menu is missing from the menu bar. When the Edit menu is absent, standard actions such as Cut, Copy, and Paste are unavailable.



The developer can add these menu items and associate them with the appropriate standard actions (see Menu item properties | 4D Docs) so that standard shortcuts like Ctrl+C / Ctrl+V (Windows) or Cmd+C / Cmd+V (macOS) work correctly in Application mode.
