图中红框框起来的是modifier,以shift为例,它包括左shift和右shift两个键,左shift键的keycode是0x32,右shift的keycode是0x3e,左shift的keysym是Shift_L, 右shift的keysym是Shift_R。无论是左还是右shift,作为modifier的时候它们的功能都是相同的,即左shift +a和右shift +a效果是一样。所以modifier shift是一个...
To make it clear, lets see an example: In american keyboard, the 16 value is the key code for Shift and the 59 value is the key code for the key ":;". So, in this scenario, to send ':' to the operational system, you should use key code 56. To send ';' you should send 16...

Key code constants are defined in this class. Scan code constants are raw device-specific codes obtained from the OS and so are not generally meaningful to applications unless interpreted using the KeyCharacterMap. Meta states describe the pressed state of key modifiers such as #META_SHIFT_ON or...
