You can align several equation objects with one another in a graphic frame, just as you align other objects. You can also align several equation objects along a manual alignment point, even when they’re in separate graphic frames.
FrameMaker maintains the alignment of the equation objects as you edit the equations. For example, if two equations are left aligned, the left alignment is maintained as the equations expand or shrink.
Select the equations to align by Control-clicking the first equation; Control+Shift-click the other equations.
Make sure that the last equation you select is the one you want to align with.
