Hi everyone,
being a newbie I just discovered how different setups for the grid may
affect my (very simple) document.
In the Details manual (which of course I don't understand because of my
unexperience) I read that many people don't use the grid, but when I
configure grid=no the whole lines of a section are printed one over the
other.
Playing with the options and setupinterlinespace I got the unhappily
desired 1.3ex that may school requieres for the teaching programs
(grid=line, interlinespace=1.3ex), but I somehow feel that's not the right
way to go.

1. Why are the lines printed one over the other when grid=no? how do profis
then use context without grid?

2. Is there a document where I can read how the grid is conceived to work
for the many options in a simple way?

thanks in advance
