typing a document- end of line wrap around goes to next line/single space,
but if I press Enter the next line double space instead of single space. how
do I change it.
If I type Max does tax and loose lips sink ships and hit enter, after tax, i
want to get:

Max does tax (press Enter)
and loose lips sink ships
NOT
Max does tax (press Enter)

land loose lips sink ships. how to change from double to single. HELP!!!!!
