ANTI-DC KEY SEQUENCES
You can prevent DCing at the end of a jam session by pressing and releasing the 3 keys in different orders.
When you start (hold the keys in this order): Alt-Ctrl-Esc.
When you end (release the keys in the order): Esc-Alt-Ctrl.
NOTE: This isn't compatible with the Task Manager technique.
THE TASK MANAGER TECHNIQUE
It is possible to go for 5 minutes without holding the buttons down. Simply start the mission, begin jamming (Ctrl+Alt+Esc), then whilst holding these three keys down, press Del. This will open the task manager. As this forces a window change, SDGO will still think you're jamming.
