Many apps for the WM5 seem to not use the left and right keys that the 700W/WX has. The ones that do use it seem to always have an option menu to exit the app.

When using ones that don't, particularly games, I can't figure out how to get out of the app! Is there a way to auto-close the application running (holding down OK doesn't work, and I tried mapping the PTT button to the Task Manager, but that didn't work either) or somehow get back to a different app when I'm stuck in an app that doesn't have an easily found exit method?
