Casio Classpad’s (fx-CP400) Hidden Shift Functions

fx-CP400 Keyboard

Hidden Shift Functions

When I was giving a quick review of the Classpad’s fx-CP400 last March (http://edspi31415.blogspot.com/2016/03/a-quick-look-at-casio-classpad-fx-cp400.html), I mentioned that I would have liked the basic scientific functions assigned and listed on the keyboard.  It turns out that most of the keys have shifted functions.  The reason why they are not listed is because the shifted functions can be customized.  Here are the default shift settings:

COPY	CUT		PASTE		UNDO		√[ ]		[ ] / [ ]
=	x		y		z		^		÷
T
(		7		8		9		*
θ		e^[ ]		ln(		log[ ]
)		4		5		6		-
|  with		sin(		cos(		tan(
,		1		2		3		+
=> store		π		i		∞		ans
(-)		0		.		EXP		EXE

To assign (or clear) keyboard assignments: 

1.  Press Menu

2.  Select System (2^nd page)

3.  On the top row of icons, select the (Shift) icon.  (first set, farthest right)

4.  Select a key.  To assign a function, select the box next to [ Set ].  Call up the keyboard if needed.  When are you ready, press [ Set ].

5.  You can clear a key by pressing [ Clear ].

6. To return to default settings, press [ Default ].

7.  When you are done with the keyboard settings, press [ OK ]. 

8.  Test your settings by going to the Main screen.

This is also shown on pg. 247 of the Casio Classpad II manual.

Here is my customized keyboard.  I made a keyboard on an index card and keep it with the Classpad.  It is great because we can easily call up commonly used functions without having to hunt through the soft keyboard.  For mine, I just kept the defaults and added some other basics to the missing keys (they are in green for reference):

COPY	CUT		PASTE		UNDO		√[ ]		[ ] / [ ]
=	x		y		z		^		÷
t		sinˉ¹(		cosˉ¹(		tanˉ¹(		{ }
(		7		8		9		*
θ		e^[ ]		ln(		log[ ]		abs(
)		4		5		6		-
|  with		sin(		cos(		tan(		arg(
,		1		2		3		+
=> store		π		i		∞		ans
(-)		0		.		EXP		EXE

Scientific Calculator Keyboard Challenge II

Feeling creative?  Ever dreamed of the perfect calculator?  Here is a chance to design a calculator.  It can cover any part of mathematics you want:

*  Scientific
*  Financial
*  Programming/Graphing
*  Algebraic and/or RPN (Reverse Polish Notation)

Or if you want to go a specialized route, like Calculated Industries, consider:

*  Construction
*  Unit Conversion
*  Gaming
*  Geometry Applications
*  Civil Engineering
*  Physics 
*  Astronomy
*  Stock Market
*  Common Every Day Applications

It can be any combination!

Rules:
*  The keyboard must be used, including the arrow keys.  Assume that the calculator will have the necessary screen size.  You have 16 blank keys, of course, you can/should consider using shift and alpha keys.
*  The keyboard has a double-wide Enter key.  RPN and Hewlett Packard fans rejoice!
*  The marked keys must remain.  

Other than that, go wild!  Leave your creation in the comments.  

Have fun!

P.S. If you want another design, I had a post where you designed a calculator keyboard using only 25 keys.  The link is here:
