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 `.
The table lists functions that include the $key. These are not programmable.
Keystroke | Definition | |
|
| |
ƒ& $ | Holding these two keys during the entire | |
libraries from being attached AND prevents 'STARTUP' from being | ||
| ||
| executed. This is useful if the calculator seems to hang up during | |
$& 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 | |
| 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. | |
