The VAR Menu
Another way to retrieve a variable is to use the VAR
(variables) menu. The VAR menu contains the Home
variables, as well as the aplet variables for the current aplet.
The VAR menu is organized by category. For each category of
variables on the left, there is a list of variables on the right.
The highlighted category is the current category.

The {{HOME}} and {{APLET}} menu keys switch to Home and
Aplet variables. The h symbol indicates what is "on": {{HOM*}}
means that the Home variables are displayed.
The Home variables are the ones you most commonly use
while doing calculations in Home. Any value (or other data)
you store must be stored in a variable of the correct type.
