There is a special cursor on top of the info box that you can switch from filled to empty symbol. The emtpy cursor allows you to select edges/surfaces individually, so with SHIFT you can select multiple or use boundary selection etc.
You can also hold CTRL + SHIFT to toggle the cursor, much like how space bar toggles the magnet.
The (old) tutorial videos for morph tool on ArchiCAD youtube channel still are great for learning tricks with morph tool. The classics remodelled and tie fighter modelling video etc are also good for picking up tricks.
