2.    Rc. means Recalculate,  input a new value for one of the known variables and Click the appropriate button while pressing the Shift key to calculate a new answer for the same unknown variable.

3.    These pale yellow buttons are the Multiple-Entry Calculators.  

4.    (^) is an abbreviation to clicking the [Enter <--] Button or pressing the Enter key on the keyboard.

5.    <>, is an abbreviation that means Convert between variables.

6.    See the Help file that comes with the RPN Engineering Calculator software for a more complete description of the available functions.
