Arrow and Function Keys

Question:

How can I trap the Arrow and Function Keys?

Answer:

Check for the correct virtual key in the KeyDown event for the
form.

Example:

procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
  if Key = VK_RIGHT then
    Form1.Caption := 'Right';
  if Key = VK_F1 then
    Form1.Caption := 'F1';
end;
