SendInput hold keyboard key down.

[taylorc8]

My intuition from working with the mouse buttons for simulating input tells me to send a key down , pause, then a key up. However, this doesn't seem to be the case for holding down a keyboard key, or maybe the application isn't detecting it for some other reason? I've also tried sending multiple key downs, followed by a key up, then keydown/keyup combinations. The application (game) WILL NOT detect it.

So, how dost one hold thy keyboard keys down with SendInput() ?
