; Name...........: $tagKBDLLHOOKSTRUCT
; Description ...: Contains information about a low-level keyboard input event
; Fields ........: vkCode              - Specifies a virtual-key code. The code must be a value in the range 1 to 254
;                 scanCode           - Specifies a hardware scan code for the key
;                 flags             - Specifies the extended-key flag, event-injected flag, context code, and transition-state flag. This member is specified as follows.
;                 +  An application can use the following values to test the keystroke flags:
;                 |$LLKHF_EXTENDED   - Test the extended-key flag
;                 |$LLKHF_INJECTED   - Test the event-injected flag
;                 |$LLKHF_ALTDOWN     - Test the context code
;                 |$LLKHF_UP           - Test the transition-state flag
;                 |  0    - Specifies whether the key is an extended key, such as a function key or a key on the numeric keypad
;                 | The value is 1 if the key is an extended key; otherwise, it is 0
;                 |  1 to 3 - Reserved
;                 |  4    - Specifies whether the event was injected. The value is 1 if the event was injected; otherwise, it is 0
;                 |  5    - Specifies the context code. The value is 1 if the ALT key is pressed; otherwise, it is 0
;                 |  6    - Reserved
;                 |  7    - Specifies the transition state. The value is 0 if the key is pressed and 1 if it is being released
;                 time               - Specifies the time stamp for this message, equivalent to what GetMessageTime would return for this message
;                 dwExtraInfo         - Specifies extra information associated with the message
