Press any key to end program help

So I'm trying to test my programming skills and learn some more about how lua works, but I've encountered a snag and I can't find a solution to it. What I'm trying to do is make a test program that once running uses parallel API to run a repeating loop of turtle.turnLeft as well as a bit of code that allows me to stop the turtle once I press any key. My problem is that usually the code will only run turnLeft once or the loop won't run at all, or I won't be able to input a key. Can I get some help solving this?

Post your Code then we can hell you .

He wants something extremely simple…

local function turn()
  while true do
    turtle.turnLeft()
  end
end

local function onKeyPress()
  while true do
    local event = os.pullEvent()
    if event == "key" then
      return
    end
  end
end
parallel.waitForAny( turn, onKeyPress )

It's important to note that the above code uses this structure:

parallel.waitForAny( turn, onKeyPress )

… as opposed to this structure:

parallel.waitForAny( turn(), onKeyPress() )

There's a big difference between passing the functions to the parallel API, and passing the results of function calls to the parallel API. The former "works", the latter does not.

Thank you very, very much KingofGamesYami and Bomb Bloke. You've helped me learn something valuable. I guess you realize that I'm kinda new to all of this, but everyone has their start right? Again, thank you very much.
