keyboard_close(3) returns to normal operation.
When in raw keyboard mode you can no longer use vga_getch(3) or vga_getkey(3) but you must use keyboard_getstate(3) or keyboard_keypressed(3).
Depending on the setting of keyboard_translatekeys(3) even in raw mode a <Ctrl>-C will cause a SIGINT. In any case svgalib will check for <Alt>-F1 - <Alt>-F10 and perform console switches accordingly.
