The Physical Constants Menu
With the Math menu open, press the PHYS menu key to see a list of physical constants,
arranged by subject. Choose a subject, then scroll to the constant you want. The name and
value of each constant is shown as you scroll through them. Press the VALUE menu key to
display just the value of each constant. Press the OK menu key to paste the constant into the
edit line or CANCL to return to the edit line.
The Program Commands Menu
Press the SHIFT of the Math key to see the two-column Program Commands Menu. The
program commands are grouped by category; the categories appear in the left column and
the commands under each category are found in the right column.
You can always type a command in letter-by-letter and the HP 39gII will accept it.
