key_shifts(3)			 Allegro manual 		   key_shifts(3)

NAME
     key_shifts - Bitmask containing the current state of modifier keys. Allegro
     game programming library.

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. Wherever possible this value will
     be updated asynchronously, but if keyboard_needs_poll() returns  TRUE,  you
     must  manually  call  poll_keyboard()  to	update it with the current input
     state. 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_COMMAND_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

     Example:

	if (key[KEY_W]) {
	   if (key_shifts & KB_SHIFT_FLAG) {
	      /* User is pressing shift + W. */
	   } else {
	      /* Hmmm... lower case W then. */
	   }
	}
