Background
Most pull-down commands, as well as certain other Network Editor activities, operate on one or more selected modules. For example, the Edit->Delete pull-down command deletes the modules that you have selected.
Selecting a single module
To select a single module, select it with the left mouse button. The Network Editor selects the module and deselects all previously selected modules. If the module is open, select its title bar or frame. Do not select the module's ports.
Appearance
A selected module's color is blue.
Lasso
You can select several modules at once by lassoing the modules. Lassoing means using the mouse to outline a rectangular region, or lasso. The Network Editor selects the modules that are completely or partially inside the region.
To select one or more modules by lassoing:
1. Point to one corner of the rectangular region you intend to outline. The pointer must be over an unoccupied portion of the window.
2. Drag the mouse pointer with the left mouse button to the diagonally opposite corner of the region. As you do, the Network Editor displays the rectangular region's outline.
3. Release the mouse button.
The Network Editor selects the modules that are completely or partially inside the rectangular region. It removes the outline and deselects all previously selected modules.
Shift key
When you select one or more modules, the Network Editor by default immediately deselects the previously selected modules.
You can alter this behavior by holding down the Shift key when you select a module. Here's what happens:
* If the module is currently not selected, the Network Editor selects it, adding it to the selection list. The selection list now consists of that module and the previously selected modules.
* If the module is currently selected, the Network Editor deselects it, removing it from the selection list.
You can use the Shift key with a lasso operation, too.
Modules in the selection list must have the same parent module. If you attempt to add a module to the selection list, but the module's parent is different, the Network Editor selects the module and deselects the previously selected modules.
Deselecting all modules
You can deselect all modules by selecting an unoccupied area in an opened window.
