The overview Bank connections shows all banks set up for you. The first bank was already set up during the First initialization. Further banks can be set up here subsequently. For this purpose see section Set up bank access.
Via the context menu there are further functions available. To do so, right click the desired bank with the mouse.
By selecting the menu item Properties the dialog box opens, which is described in the Bank properties section. This you can also reach with a double-click, via the Edit menu or the key combination Alt+Enter.
