keyboard_translatekeys3

Usage

Overview

This function sets several flags which control how certain scancodes are mapped. At startup a mask value of 0 is active.

mask must be a logical or of zero or more of the following #predefined integers to turn the features listed on:

TRANSLATE_CURSORKEYS

Translate the scancodes of the SCANCODE_CURSORBLOCK* keys to those of the cursor keys on the number pad, s.t. keyboard_getstate(3) and keyboard_keypressed(3) report a keypress of the corresponding number pad cursor key and not the one on the cursor block.

TRANSLATE_DIAGONAL

Translates the scancodes of diagonal cursor keys (keypad 7, 9, 1, 3) to presses of two of the ordinary up, down, left, right keys. For example, instead of reporting a press of SCANCODE_CURSORUPRIGHT keyboard_getstate(3) and keyboard_keypressed(3) report a simultaneous press of SCANCODE_CURSORUP and SCANCODE_CURSORRIGHT.

TRANSLATE_KEYPADENTER

The scancode of the keypad enter key is mapped to that of the ordinary enter key, s.t. keyboard_getstate(3) and keyboard_keypressed(3) report a press of SCANCODE_ENTER regardless if keypad enter or ordinary enter is pressed.

DONT_CATCH_CTRLC

Pressing <Ctrl>-C does not raise a SIGINT. On contrary to the other flags this has also effect when a user defined keyboard event handler is used. Svgalib will always process <Alt>-F1 - <Alt>-F10 and perform console switches accordingly.
