Just got a playbook last Friday (1 week ago) and was exploring the many shortcuts with swipe commands. Accidentally, I did the multitasking swipe command followed by a random touch/swipe. I was then able to control that specific application (web browser) while in multitask; however, after exiting that app, i was unable to control other apps while in multitasking.
Was this just a glitch? or is there a swipe command/function that does this? =/
nope, only controlled that specific app (web browser); didn't explore too much as i was more keen on trying to replicate the swipe command. Unfortunately, no luck =/
