Microsoft Access - Maintain Alignment When Moving Controls (Access 97/2000/2002)
Although the ability to drag controls to a desired place on a form or report provides you with flexibility, it's also a source of frustration. You'll often want to move a control in on direction and accidentally drag it diagonally. Fortunately, it's easy to restrict a control to just horizontal or just vertical movement. To do so, press the [Shift] key before selecting the control. Then, simply drag the control in the appropriate direction. Based on the initial direction, you'll only be able to move the control left and right or up and down.
