One of the most common tasks in the Main view is to select items. Using the Selection Tool (Arrow button on the main toolbar) you can select and move items in the design page. Select items by clicking on them. This will place ‘handles’ and a dotted line around the selected items.
You can also see that items are selected by looking in the Objects view. Another way to select items in the Main view is to drag a rectangle around those items. Anything completely in the rectangle will be selected. However, if an object is grouped with something outside the rectangle, it will not be selected.
