Grid paper.png  Example
The program adds an event which it will eventually pull.
Code
os.queueEvent("abc", 2, "meow")
   while true do
   local event, param1, param2 = os.pullEvent()
   if event == "abc" then
      print("ABC EVENT! Parameters: "..param1.." / " ..param2)
   else
      print("Event: "  .. event )
   end
end


Grid paper.png  Example
To easily have a redstone and a key input do the same,
it queues a key event with the appropriate key if a redstone event happens.
Code
while true do
    local event, param1 = os.pullEvent()
    if event == "redstone" then
      if rs.getInput("left") then
        os.queueEvent("key",28)
      end
    elseif event == "key" then
      if param1 == 28 then
        print("Hello")
      end
    end
end
