key_shifts

SYNOPSIS
#include <allegro.h>

extern volatile int key_shifts;

DESCRIPTION
Bitmask containing the current state of shift/ctrl/alt, the special Windows keys, and the accent escape characters.

This can contain any of the flags: KB_SHIFT_FLAG KB_CTRL_FLAG KB_ALT_FLAG KB_LWIN_FLAG KB_RWIN_FLAG KB_MENU_FLAG KB_SCROLOCK_FLAG KB_NUMLOCK_FLAG KB_CAPSLOCK_FLAG KB_INALTSEQ_FLAG KB_ACCENT1_FLAG KB_ACCENT2_FLAG KB_ACCENT3_FLAG KB_ACCENT4_FLAG
