SYNOPSIS

#include <agar/gui.h>

DESCRIPTION

The AG_KeySym type describes virtual keyboard keys, covering the ASCII range in addition to some common function keys. Physical keyboard scancodes are mapped to AG_KeySym values in a platform-dependent way by the underlying Agar driver (which may or may not generate a Unicode character as well). In general, Agar developers should reference things such as user-configurable function keys and keyboard shortcuts using AG_KeySym values as well as Unicode character values.

The functions AG_LookupKeyName(3) and AG_LookupKeySym(3) may be used to convert between numerical and string representation.
