If Snap To Grid is turned on, when you create a control by clicking the form, report, or data access page, Microsoft Access aligns the upper-left corner of the control to the grid. If you create a control by dragging, Access aligns all corners of the control to the grid. If you move or resize an existing control, Access lets you move the control or its boundary from grid point to grid point only.
When Snap To Grid is turned off, Access ignores the grid and lets you place, move, or resize controls anywhere on the form, report, or data access page.
Tip If you want to turn Snap To Grid off temporarily, hold down the CTRL key before or while you're placing, moving, or sizing a control. Releasing the CTRL key turns Snap To Grid back on.
