This code allows you to change the Keyboard speed (0 to 31) and delay (0 to 3).. useful in games or as an alternative to using the keyboard control panel.
Assumes
In your own code use SetFastKeyboard() to change to your new speed and RestoreKeyboard() to change back to thier previous defaults.
Side Effects
On my computer when my old settings are restored they are restored to speed 0 and delay 0.. after much research i determined that the value being read from the API is 0 and 0.. or my variables can't hold the values being returned.. Anyone with more info on the API or the syntax of SPI_GETKEYBOARDDELAY and SPI_GETKEYBOARDSPEED please email me.. :)
