is full of help. You might even say it is helpful.
It provides
two kinds of Help. Each screen has its own help information (accessed
from the menus by tapping Help | Screen Help or for popup windows tapping
on the 
icon). This
is called "context sensitive help"
In addition,
you can find out what each item on a given screen is there for by entering
Help Mode.
To enter Help Mode from any major screen, simply tap
Help | Help Mode in the menu or enter the shortcut / H to turn help on.
When Help Mode is on, any item on the screen can be touched, and a help
bubble describing the item you selected will appear on the screen. To
exit Help Mode, go to the help menu (it will now be the only menu visible)
and select Exit Help or use the Graffiti shortcut /x.
