Post tokey function
Hi,

This is a little function I made that could be useful to anyone making things that are triggered by pressing a key: it automatically converts the key to its number, sparing you the inconvienience of having to go through the key list and making it easier to modify. So here it is:
Code:
function tokey(n)
   local KeyTable = {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","0","1","2","3","4","5","6","7","8","9","num0","num1","num2","num3","num4","num5","num6","num7","num8","num9",".",".",".",".",".",".",".",".",".",".",".",".",".",".",".",".",".","back","tab","enter",".",".",".",".","<",".",".",".","space","insert","del","home","end","pageup","pagedown","arrowleft","arrowright","arrowup","arrowdown"};
   local i = 1;
   while i <= 85 do
      if tostring(n):lower() == KeyTable[i] then
         return(i);
      else
         i = i+1;
      end
   end
   return 0;
end


Here is an example of how it works:

user:
print( tokey('s') );
computer:
PRINT: 19

Feel free to use it and modify it as you like.

I like this, it's a good idea. We need more time-conserving functions like this one.
