Where is the "Codetools" section?

If your signature is up-to-date (Laz 2.2.4), open the options
from the main menu then look at the Tree on the left. (With that old Lazarus it is only there if you go via main menu)
Otherwise, it is in that tree, even if you open via editor context menu.
Or follow the link, on the "tab and indent" page.
