Supports can be copied and moved using drag & drop, even if the "Move/Copy" function is not available in the shortcut menu. This applies to all kinds of supports: nodal supports, line supports, and surface supports. These can easily be assigned to further nodes, lines, or surfaces.
You can move and copy objects directly in the display window in order to work more efficiently. If this feature is not desired by the user, you can simply disable it. To do this, right‑click in the display window and select the "Enable Drag & Drop" entry in the shortcut menu.
