SYNOPSIS

#include <agar/core.h>
#include <agar/gui.h>

DESCRIPTION

The AG_KeyMod type describes a modifier key (or the state of all modifier keys); it is defined as:
typedef unsigned int AG_KeyMod;

#define AG_KEYMOD_NONE		0x0000
#define AG_KEYMOD_LSHIFT	0x0001
#define AG_KEYMOD_RSHIFT	0x0002
#define AG_KEYMOD_LCTRL		0x0040
#define AG_KEYMOD_RCTRL		0x0080
#define AG_KEYMOD_LALT		0x0100
#define AG_KEYMOD_RALT		0x0200
#define AG_KEYMOD_LMETA		0x0400
#define AG_KEYMOD_RMETA		0x0800
#define AG_KEYMOD_NUMLOCK	0x1000
#define AG_KEYMOD_CAPSLOCK	0x2000
#define AG_KEYMOD_MODE		0x4000
#define AG_KEYMOD_ANY		0xffff
#define AG_KEYMOD_CTRL		(AG_KEYMOD_LCTRL|AG_KEYMOD_RCTRL)
#define AG_KEYMOD_SHIFT		(AG_KEYMOD_LSHIFT|AG_KEYMOD_RSHIFT)
#define AG_KEYMOD_ALT		(AG_KEYMOD_LALT|AG_KEYMOD_RALT)
#define AG_KEYMOD_META		(AG_KEYMOD_LMETA|AG_KEYMOD_RMETA)

The method of accessing key modifier states (and the related translation from native scancodes to AG_KeyMod) is driver-specific.
