>>In a text box control I need to determine the user action that triggered either When or GotFocus events: was it TAB key, Left Mouse click or Right mouse click? LASTKEY() doesn't return mouse clicks, neither does KeyPress. When and GotFocus events fire before Click or RightClick; MouseDown doesn't fire at all in this scenario, so far as I can determine; and the MouseEnter nButton parameter returns zero, regardless of which mouse button is used.
