how can I view the ordinal numbers of the keys? I know ESC is 27, but
how can I parse them into a loop so I can see each key?

open the unit lcltype and locate the constant vk_unknown. you will
find all the key codes there. If you insist on finding for your self
then create a new application and write a keydown event for the main
form. the parameter key has the code you are looking for.

Or if you use FPC only (console) (I saw in the other topic you used
Linux FP console)

Notice that some keys (like the arrowkeys) are actually two keys.
First #0 and second a positive number.

So if you are going to read those keys you need to take the special #0
value into consideration and read the second key and act upon it.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
project1;uses Crt;var  Key: Char;begin  repeat    Key := ReadKey;   
WriteLn('You pressed ', Ord(Key));  until key = #27;end.
