local event, k1 = os.pullEvent("key")
if k1 == 2 then
   do stuff related to the 1 key being pressed
end

Remember though, ranks are just "fun things" they have no reflection of your actual abilities/knowledge.

But at 1000 posts you can request your own title :)/>/>

So only 980 posts before I can request "Prefers C++"…

But please don't trade quality for quantity, just to get a custom title.
Because by the time you've posted hundreds of not-so-useful posts and got your title, people will definitely be much more annoyed about that fact than care for your title. :(/>/>

EDIT: And this was not specifically directed at you, but more a plea to everyone whom it may concern. So no offense!

Try using key events

local event, k1 = os.pullEvent("key")
if k1 == 2 then
   do stuff related to the 1 key being pressed
end

Isn't there a more efficient way to do this? Even for the first key, there is such a delay that my finger is already off the key when the command occurs. If I have many keys to use, that if/elseif is gonna become very slow for the last ones. Can't I directly assign a key like "q=print("hello")?

local bindings = {
  ["q"] = function() -- however you play the note q is on end,
  ["w"] = function() -- however you play the note q is on end,
}

while true do
  local event, char = os.pullEvent("char")
  if bindings[char] then
    bindings[char]()
  end
end

Talking about coding a piano here so I have a IF for letters Q to P for now and it's pretty slow. I think it's the normal ComputerCraft lag when you type so there really isn't much we can do.
