2.3.2.1 Get Key Response (#R)

The Get Key Response is the classic response command. It pauses Cogsys until the subject presses a key. It then writes the key pressed and the reaction time in milliseconds to output, followed by a newline. It updates Cogsys variables COGVAR_KEY and COGVAR_TIME with the key and time, respectively.

Like most response commands, Get Key Response will terminate execution of the experiment if the BREAKOUT_CHAR key is entered.
