Ever been a flight leader patrolling one of your factories and bridges? You shoot down the incoming bombers but hate how autopilot keeps you over the target for a long while more? Well fear no more, once you kill those bombers press Ctrl+H and have the auto-pilot return you to base
Also
Have you ever been in a fight with escorts, and see the bombers slipping away as you deal with the scouts? Well just F8 onto one of those bombers and press Ctrl+E and watch as your wingman gives pursuit, ignoring your cries of enemy on your six lol
