It is very easy to create neatly organized keyboard layouts by using the grid alignment tools. These tools allow you to show a grid on the screen, and have the controls snap to the grid as you move them. This makes it very simple to align controls into neat rows and columns.
To enable the grid alignment tools, go into Design Mode, and select Layout Settings. In the Alignment Grid section you can show or hide the grid, enable or disable grid snapping, and set the spacing of the grid.
