Keystroke values are the values returned by the GetKey command to indicate which button was pressed.



The TI-84 getKey function uses a map exactly like this to detect which button was pressed. It is much like a graph, starting with (1,1) and ending with (10,5)

The value ends up to be a 2 or 3 digit number with the row number (starting from the top) being the 1st (or 2nd, in the case of row 10) number and the column number being the 2nd number.

Y= is 11
Enter is 105
2nd is 21, etc.


Keystroke values are more complex in TI-89 since TI-89-BASIC gives support to 2ND, 3RD, Alpha and ↑ keystrokes.
