S 5 key set
Tapping the 5 key displays keys for inputting single-character variables, and changes the
5 softkey to (. You can tap this key to toggle between 5 and the initial 2D keyboard.
Tapping the $ key switches to a key set for inputting upper-case single-character
variables.
Tip
• As its name suggests, a single-character variable is a variable name that consists of a single
character like “ a ” or “ x ”. Each character you input on the 5 keyboard is treated as a single-
character variable. You cannot use the 5 keyboard to input multiple-character variable names
like “ab” or multiple-character strings. You must use the alphabet (abc) keyboard when you want
to input a multiple-character string. For more information, see “Using Single-character Variables”
on page 1-6-12.
• For information about the # key that appears in the lower right of all of the 2D keyboard key
sets, see “Using the Answer Variable (ans)” on page 2-2-2.
• Note that natural input is available in most applications of the ClassPad. Natural input cannot be
used in the geometry measurement box or when entering data into a list.
