How do you set the heading in the autopilot for the FSX default 737-800? I can't find any heading bug knob or similar to do this and the course setting knob does not slave to the heading setting. I don't want to mess with the keyboard commands (i.e. ctrl-shft-h, +/-). I want to be able to do this with my mouse in the cockpit.Thanks in advance for your help.

Never mind - finally figured it out. Clicking on the centre of the banklimit knob does it, althought it does not seem to be properly documented in the Learning Center.
