Key Modifiers

KeyModifiers are a set of Ruby integer constants that represent modifying control keys that may be pressed alongside normal keys. These values may be returned, for example, by methods in KeyEvent.

Key Modifier Constants

The following key modifier constants are defined:


    MOD_NONE      = 0x0000,
    MOD_ALT       = 0x0001,
    MOD_CONTROL   = 0x0002,
    MOD_ALTGR     = MOD_ALT | MOD_CONTROL,
    MOD_SHIFT     = 0x0004,
    MOD_META      = 0x0008,
    MOD_ALL       = 0xffff
    MOD_CMD       = Platform Specific

Note: On Mac OS X, MOD_CMD is the same as MOD_META, while on other platforms, it is the same as MOD_CONTROL. In portable code, MOD_CMD should be used instead of MOD_CONTROL to account for the fact that although the Control modifier exists under Mac OS X, it is not used for the same purpose as under Windows or Unix.
