Check for a keypress

[Jose Torre-Bueno <jtorrebueno@...>]

Is there a way from inside Lua to check whether any key has been pressed?  io.read() will get a line from the console but if there is no input it pends waiting for input.  I would like to be able to write a test that gets input if any is ready but would continue if there is none.  It is not obvious to me if this can be done at all.
