How do I add more than one object at a time?
When selecting a mode, such as Tools => Add Port, you will remain in the mode until you add one port to the circuit. After adding a single port, the project editor will then automatically return to pointer mode. If you wish to continue in the Add Port mode in order to add multiple ports, then hold the shift key down while selecting Add Port mode from the menu with the mouse. You will continue in this mode until you select another mode from the menu bar or press the Escape key which will place you back in pointer mode, the default startup mode, which allows you to edit your circuit.
Note that shift selecting a mode applies to all methods of entering that mode, including selection of an icon from the tool bar or tool box, or use of a shortcut key. Also, when using an icon button to enter a mode, double clicking on the icon acts the same as pushing the shift key.
