Both keys can be read using the ReadKey() function. The escape key has a value of #27, while the function keys consist of two chars: #0 and another. Here is a small program, which allows you to read a single keypress and return its value:
[code]
var
ch: char;
begin
ch := readkey;
if ch = #0 then begin
ch := readkey;
writeln('Extended key: ', ord(ch));
end else
writeln('Simple key: ', ord(ch));
end;
[/code]
