I need to change my default margins. Being visually impaired, I need as
much writing space as possible to get the very large text on, and anyway,
don't see the point in wating an inch all round for casual files. but the
damn system tells me that changing the right margin might give uneven colums,
like I give a toss! and I can't find a way round that to set the margins as I
want them. Help, polease????
