Continuing with setting up application preferences,
make sure there are no open documents and click Edit
> Preferences > Document. This may seem a
little confusing (because you clicked Edit > Preferences
> Document) but remember that any preferences
you setup with no open documents will become the application
defaults. It's just that these preferences are accessed
by these mouse clicks.
1. On the "General" tab, select points for
both horizontal and vertical units of measurement. Make
sure "Points/Inch" is set to 72. I prefer
my guides to be "In Front" and I'll accept
the remaining dialog defaults.
2. I keep the "Paragraph" tab defaults...
3. Ditto for the "Character" tab...
4. Skip the "Tool" tab for now...and accept
the defaults for "Trapping".
