variable—whether Home, app, or user—by entering its
name in Home view and pressing
E. You can enter
the name letter by letter, or choose the variable from the
Variables menu by pressing

the Vars
menu
Besides the four variable menus, the Vars menu contains
a toggle. If you want the value of a variable instead of its
name when you choose it from the
Vars menu, tap
. A white dot will appear next to the menu button
label to indicate that it is active and that variable values
rather than names will be returned upon selection.

the app variables
menu. (If you were
interested in a Home

3. Use the cursor keys
to navigate to the variable of interest.
4. Press
W to see the
help about that
variable.
5. Tap to exit or
