Use F6. This sets the A/P heading lock to 'true-heading-mode' and causes /autopilot/settings/true-heading-deg to be updated to the appropriate heading for the current waypoint, if any is set. If no waypoints have been entered you can set /autopilot/settings/true-heading-deg manually, either via the property browser, the A/P gui (there are some quirks, at least to my mind, in the way the A/P gui works) or by the <- & -> cursor keys. When the A/P heading lock is set to 'true-heading-mode' the appropriate set of controllers in the A/P should engage and start steering the a/c.
