Selecting Multiple Menu Items
As you create your menus, there will be times when you need to select multiple menu
items, such as buttons, drop zones, or text objects, so that they can all be moved, deleted,
or have an attribute applied. The usual way of dragging to select a group of items will
not work—you will end up creating a new button.
To select multiple menu items
Do one of the following:
To individually select items, hold down the Shift key and click them.
To select a group of items by dragging, press the Command key while dragging over
them. Any currently selected items are deselected first. Press the Command-Shift keys
while dragging to keep any currently selected items selected.
To select all items in the Menu Editor, press Command-A.
To deselect all items, press Command-Shift-A.
