So the escape key is actually a back button which loads pages from the cache?
I thought escape == close in the BlackBerry world.
In the blackberry World, Esc = close the page and go to previous page.
for example in the Media application, if you are listening to a song : hit Esc => go to song list hit est => go to album list hit esc => go to artists list hit esc => go to filter list hit esc => go to media type chooser hit estc => closes media app.
The search box on top-right of this page is your true friend, and the public Knowledge Base too:
