To transmit your whole module, in Product Explorer view open context menu for as_dev_tools_application module and then click Session > Load Module. You can also transmit module to a session with the use of Drag & Drop feature by just simply dragging module and dropping it on a session element in Product Explorer view or on a related GIS Console view.
NOTE: To perform load/transmit element from Magik Editor with the use of drag & drop, you have to click & hold mouse middle (scroll) button instead of left mouse button.
NOTE: Load Module function is enabled if project has assigned a session and the session is started. Creating a session was covered in this tutorial.
