For many actions, including editing, moving, aligning, and grouping, you need to select one or more objects in an interface. You can only multiply-select siblings--objects that are children of the same parent. (All windows in a project are siblings, for instance, as are panes in a window and control objects in a single control pane. Panes that are dropped on a control pane and created as children of the control pane function like control objects in the control pane.)
You can select objects in the interface or in the Module Browser. See "Module Browser" for a description of the Browser. See "Editing Objects in the Interface or in the Browser" for information about cutting, copying, and pasting interface objects.
Only control objects can be grouped or aligned (using the Align and Distribute functions).
Select a single window (main window, custom dialog, or file selection dialog box) by clicking mouse button 1 on the object in the Browser or in the interface (click in the status area at the bottom of the window object).
Select an additional window by clicking mouse button 2 on the window in the browser or in the interface.
Select a single pane by clicking mouse button 1 on the pane in the Browser or in the interface.
Select additional panes in the same window by clicking mouse button 2 on the pane in the Browser or in the interface.
Select one object by clicking it in the interface or in the Module Browser.
Select a number of adjacent objects by positioning the mouse cursor above and to the left of the objects, pressing mouse button 1, and dragging the mouse to encompass other objects down and to the right of the first object.
Add or subtract an object to the current selection by clicking mouse button 2 on the object.
If an object is selected, clicking mouse button 2 on it deselects it.
To add a number of adjacent objects to those that are selected, position the mouse cursor above and to the left of the objects to be added, press mouse button 2, and drag the mouse to encompass other objects down and to the right of the first object.
Only that object will be selected.
When you have selected a number of objects in the interface, all the objects will move if you press mouse button 1 on one of the objects and move the mouse. A rectangular border will be drawn around the objects as you move the mouse.
