A quick tip hot to put more than one line y the hint property
Here is a quick tip!
If you want to have more than a single line hint on a control,
for example in a button, put it's ShowHint property to true but
don't put anything in it's hint property. Then, in the FormCreate
event of the form just do this:
procedure TForm1.FormCreate(Sender: TObject);
Button1.Hint := 'First line'+chr(13)+'Second line';
