The Layout menu Alignment command accesses a submenu of commands that enable you to align selected groups of controls.
The Alignment submenu commands are listed in the following table.
| Command | Toolbar Button | Description | 
|---|---|---|
| Left |   | Aligns to the left edge of the master control | 
| Right |   | Aligns to the right edge of the master control | 
| Top |   | Aligns to the top edge of the master control | 
| Bottom |   | Aligns to the bottom edge of the master control | 
| Centre Horizontally |   | Centers the selected controls horizontally | 
| Centre Vertically |   | Centers the selected controls vertically | 
You cannot select the Left, Right, Top, and Bottom commands if you have not yet selected a group of controls (that is, they are disabled). You can align controls across frame container controls, if required. For more details, see "Alignment Command", later in this chapter.
