G. Keyboard Shortcuts

Each key on the calculator performs so many different functions that only the most fundamental ones are actually shown on the keyboard (on the keys themselves or on the space around the keys). The following is the complete list of the “hidden” functions of the calculator’s keyboard.

Notation: In this appendix, there are two ways of showing key presses:

@`means: press Right Shift, release it, then press `.

@&`means: while holding Right Shift, press `.

On-key combinations

The table lists functions that include the $key. These are not programmable.

Keystroke

Definition

 

 

ƒ& $

Holding these two keys during the entire turn-on routine prevents all added

libraries from being attached AND prevents 'STARTUP' from being

 

 

executed. This is useful if the calculator seems to hang up during turn-on.

$& C

Warmstart. Clears the stack, PICT, LASTARG, and other temporary things

 

like those, and turns off USER Mode. Doesn’t clear any variables. Useful

 

when the calculator is taking too long to finish a complicated function and

 

pressing $doesn’t seem to interrupt it. Also useful if you lock out the

 

keyboard with a bad USER mode set of key assignments.

$& D

Displays the current ROM’s version and build numbers, then enters Factory

 

Test Mode. Press $& Cto exit

$& F

Like $& Dbut a friendlier and more complete set of tests, designed for

 

the end-user. Follow the instructions on the screen. Do NOT format the SD

 

card unless you wish to lose all of its contents!

$& A& F

Clears the calculator’s RAM, returning everything to the factory state.

 

Anything in port 2 (flash ROM) will remain untouched.

$&

Print Screen. Send the current display to the current printer

$& +

Adjusts the display contrast up.

$& -

Adjusts the display contrast down.

$& R

Begins a “remote control” mode, where the calculator transmits the screen

 

bitmap through the USB port and accepts keypresses through the same way.

$& S

Terminates the remote control mode.

$& Ó ($&9)

Forces the very next system interrupt to be ignored. This is intended to allow

 

the user to shutdown rapidly repeating alarms, but it must be noted that

 

keystrokes also cause a system interrupt, so be sure NOT to press any key

 

between pressing $& Ó and the next repeating alarm, or the alarm

 

will come due and continue repeating.
