Calamus offers the option to
magnetize the edges of the
frames you create in the page layout. This very practical feature is
often forgotten, unfortunately, and other ways are looked for to align
various frames with each other. You can set the distance over which
this magnetization is effective in the Magnetic frame range dialog of
the previous function group.
If you switch on this icon to make the magnetic frame range
visible, dotted outlines both inside and outside every frame let you
see immediately the areas where the magnetic
field will make
frames snap to each other.
If you never use this function you naturally do not have to switch it on, specially as it slows down screen redraws and may cause confusion with other elements on the page.
