Keycode Reference

The Prizm's syscalls and related keyboard functions use different methods of representing keys. These values vary in size and are tied to specific groups of syscalls. The Reading Input tutorial page has information on such syscalls and their uses.

Matrix Key Codes

Matrix Hexadecimal Codes
F1 070A	F2 060A	F3 050A	F4 040A	F5 030A	F6 020A
Shift 0709	Optn 0609	Vars 0509	Menu 0409	0209 ▴ ◂ 0309   ▸ 0208 ▾ 0308
Alpha 0708	𝓍² 0608	^ 0508	Exit 0408
X,θ,T 0707	log 0607	ln 0507	sin 0407	cos 0307	tan 0207
ab/c 0706	F↔D 0606	( 0506	) 0406	, 0306	→ 0206

7 0705	8 0605	9 0505	DEL 0405	AC/ON 0101
4 0704	5 0604	6 0504	× 0404	÷ 0304
1 0703	2 0603	3 0503	+ 0403	- 0303
0 0702	. 0602	EXP 0502	(‒) 0402	EXE 0302

The matrix key codes are a 2 byte column/row pair specified as 0xCCRR. These correlate to the column and row of the keyboard matrix that the key is located at. The following functions use this key format:

• GetKeyWait_OS
• Keyboard_PutKeycode (first two parameters)

The two tables in this section show the same information, presented in different ways.

Program Key Codes

Program Codes

7 74	8 64	9 54	DEL 44	AC/ON 10
4 73	5 63	6 53	× 43	÷ 33
1 72	2 62	3 52	+ 42	- 32
0 71	. 61	EXP 51	(‒) 41	EXE 31

The key codes here are decimal values made up of the column and row as CR. The following functions use this key format:

• PRGM_GetKey - Function to emulate legacy functionality, see PRGM_GetKey_OS for definition.

Character and Control Codes

Character codes are not directly mapped to the physical keys on the keyboard. The values use the state of key modifiers to return a value pertaining to the specific function of a key (pressing EXIT returns a code that's different from when pressing SHIFT then EXIT). The following syscalls use these codes:

• GetKey
• Keyboard_PutKeycode (third parameter)
• EditMBStringCtrl and variants
• EditMBStringChar and variants

The values in the tables below are in hexadecimal.

Notes

• The values of the characters in Alpha mode are the same as their ASCII codes, both for upper- and lower-case.
• Certain keys have a different value when modifiers are on, even when there is nothing printed on the keyboard to indicate such. Examples include Shift+Optn and Shift+cursor keys.
• Control codes start at 0x7530 (decimal: 30000) and are meant to be redirected to syscalls such as EditMBStringCtrl; character codes are much lower values and should be redirected to syscalls like EditMBStringChar.
