You can select items within the MontiVision Workbench by clicking the item with the left mouse button. Should you want to select more than one item, hold down the Ctrl-key on your keyboard and click on all the items you want to select. You can select items using a selection rectangle as well, by clicking on the left mouse button and dragging the rectangle around all the items you wish to select. If you only want to select filters, then press the shift-key as well.
The shift-button disables the selection of an item with a mouse click. This is helpful when you want to move more than one item. Select all items you want, press the shift-key and press the left mouse button. Now you can move all the selected items.
The application menu contains additional commands to select filter or connections.
