Keyboard

Overview

All Simulator functions are accessible from the keyboard. You can access the primary functions, like the digits or the square root function, with a single keyboard key. Other functions, especially the secondary functions, require a sequence of two or more consecutive keys.

In addition to key sequences, shortcuts are available for some common and often used functions. Shortcuts should be more intuitive and easier to remember in some cases. For example, to run a program with label A you can key in the sequence F3 Q or you can use the shortcut AltA.

The following table gives an overview on how key sequences and shortcuts are organised:

Key/Sequence/
Shortcut
Description
key Primary functions of the HP-15C keys. There are also a few secondary functions, e.g. % and π, whichÑ— are mapped to a single key.
F key Gold secondary functions.
G key Blue secondary functions.
Altkey Pop-up menus and shortcuts for secondary functions.
F1F12 Function keys. Program related commands.
Ctrlkey Interaction with the operating system.

Mac OS X specifics

Under Mac OS X the Ctrl key is replaced by the key.

Keyboard HP-15C key Function
# f RAN # Generate a random number.
! f x! Factorial of the number in the X register.
 space  f PREFIX Displays all ten significant digits of the number in the X register.
The display changes as long as you hold the space key pressed. When you release the key, the display switches back to the current display format.
% g % Computes the percentage X of the value in the Y register.
< , > x↔y Exchanges the contents of the X and Y register.
C COS Computes the cosine of the number in the X register.
E ex Computes the exponential function of the number in the X register.
ShiftE EEX Enter EXponent. Allows you to enter the exponent of the number in the X register.
H f HYP Prefix for hyperbolic functions. Must be followed by S, C or T or click SIN, COS or TAN respectively.
AltH g HYP-1 Prefix for inverse hyperbolic functions. Must be followed by S, C or T or click SIN, COS or TAN respectively.

ShiftI f I Access to index register as part of a keysequence, e.g. f x↔ I.
See also Complex Math below for other usages of ShiftI.
L g LSTx Rolls up the stack one register and writes the contents of the LSTx register to the X register
P g π Returns the value of π.
Q √x̅ Computes the square root of the number in the X register.
S SIN Computes the sine of the number in the X register.
T TAN Computes the tangent of the number in the X register.
X 10x Computes 10 to the power of the number in the X register.
Y yx Computes Y to the power of X.
Alt<
Alt>
f x↔ Must be followed by a valid data storage register. Exchanges the contents of that register and the X register.
AltX g Computes the square of a number.
Alt
Alt+
CHS Changes the prefix of the number in the X register.
\ , Alt/ ⅟x Computes the inverse of the number in the X register.
| (Pipe) g ABS Computes the absolute value of the number in the X register.
Ins Σ+ Accumulates the numbers in the X and Y register to the statistic sums in the data storage registers R2 through R7.
Del g Σ− Removes the numbers in the X and Y register from the statistic sums in the data storage registers R2 through R7.

Complex Math

Keyboard HP-15C key Function
G 4 8 g SF 8 Switches the HP-15C into Complex mode.
G 5 8 g CF 8 Switches Complex mode off.
I f (i) Displays the imaginary part of the complex number in the X register.
The imaginary part is displayed as long as you hold the key pressed. When you release the key the real part of the number is displayed again.
J , ShiftI f I Upper case i. Takes the Y and X register from the real stack and creates a complex number Y+iX
Tab f Re↔Im Exchanges the real and the imaginary part of the complex number in the X register. If Complex mode is not active, it is switched on.
F 1 f →R The X register must contain a complex number in polar coordinates. This function then computes the rectangular coordinates.
G 1 g →P The X register must contain a complex number in rectangular coordinates. This function then computes the polar coordinates.

Data Storage Registers

Keyboard HP-15C key Function
M STO STOre. Must be followed by a valid data storage register. Copies the contents of the X register to the given register.
R RCL ReCaLl. Must be followed by a valid data storage register. Copies the contents of that register to the X register.
AltM B3STO Invokes the store pop-up menu. Selecting a register from the menu copies the contents of the X registers to the selected register
AltR B3RCL Invokes the recall pop-up menu. Selecting a register from the menu copies the registers contents to the X register.

Edit and Format

Keyboard HP-15C key Function
U f USER Toggles User mode on/off.

User mode changes only the behaviour of the screen buttons but not that of the keyboard keys. A click on ex in User mode will run the program with label B. Pressing E always calls the exponential function.

⟵  Run mode: Deletes the last digit typed in or clears the X register if the input is completed.
PRGM mode: Deletes the current program line.
Esc g CLx Clears the X register and sets it to zero.
ShiftEsc - Clear all. Sets all registers to zero. This is the combination of f REG and setting the stack registers and the LSTx register to zero.
Disabled in PRGM mode.

Wheel fwd
g R↑ Roll up the stack one register.

Wheel bwd
R↓ Roll down the stack one register.
Alt.
Alt,
ON . Toggles the representation of the decimal point and the digit separator.

Menus

Keyboard HP-15C key Function
AltF B3F? Flag menu.
AltM B3STO Data storage registers menu in storage mode.
Selecting a data storage register from the menu copies the contents of the X to that data storage register.
AltO , F10 B3ON ON menu.
AltR B3RCL Data storage registers menu in recall mode.
Selecting a data storage register from the menu copies the contents of that register to the X register.
AltS B3–display In Run mode, this will pop up the stack menu and the program menu in PRGM mode.
AltT B3TEST Test menu with ten compare functions.
Not available in Run mode.

System Integration

Keyboard HP-15C key Function
CtrlC B1–display
double-click
Copies the contents of the X register to the operating systems clipboard.
ShiftCtrlC Copies the contents of the X register in the current display format.
For example, if the format is set to f ENG 4, the result of 7 g LOG is displayed as 845,10 -03.
ShiftCtrlC will copy this as 845,10e-03, whereas CtrlC will copy it as 0,8450980400142568
CtrlE - Export program to HTML.
CtrlV
B2
- Copies the operating systems clipboard contents to the X register. If the contents can not be converted into a valid floating-point number, nothing is copied.
CtrlM - Saves the current Simulator memory to the memory file.
CtrlL - Reloads the previously saved Simulator memory from the memory file.
CtrlO - Open a program file.
CtrlR - Reset the memory of the Simulator.
CtrlS - Save program to a file. The default file type is '.15C'
CtrlT - HP-15C stays on top of other applications on the desktop even if it hasn't the focus.
CtrlQ - Exit HP-15C.

Program (Run mode)

Keyboard HP-15C key Function
CtrlF1
ShiftF1
- Display the help file for the current program (if available).
F2 GTO GoTO. Must be followed by a valid program label. Positions the program pointer on the label but does not run the program.
F3 GSB GoSuB. Must be followed by a valid program label. Runs the program with the given label.
To run a program with label A you must key in F3 Q and not F3 A. This is because A is a secondary function to key √x̅, which is mapped to Q.
F4 g RTN ReTurN. The program pointer is moved to step 000.
F5 R/S Run/Stop. Either runs or stops a program.
F9 g P/R Program/Run mode. Switches to PRGM mode.
Mac OS X: CtrlF9
F11 - Toggles program mnemonics in menus on/off.
Mac OS X: CtrlF11
AltF11 - Toggles coloured program menus on/off.
F12 - Opens the Program Description dialogue box. Used to edit/enter program documentation
g BST Backward STep. The program pointer is moved back one step.
SST Single STep. The program pointer is moved forward one step. This allows it to execute a program step by step.
While the key is pressed, the display shows the next step but does not executed it. The step is executed only when the key is released.
AltAE f AE Runs the program that starts at the given label.
Alt09 GSB 09 Runs the program that starts at the given label.
There are no shortcuts for labels higher than 9.
- B3GTO Pops up the program menu. Selecting a program step positions the program pointer on that step.
This is equivalent to the real HP-15C sequence GTO CHS # # #, where "#" means a digit key. This sequence is not supported by the Simulator.
