To relocate the Multi window tray:
1. Enable the Multi window feature. (See "Enabling Multi
Window" on page 27.)
2. Touch the tab to display the apps tray (containing the
scrollable apps).
Note: Notice that when the apps are visible, the tab turns a
dark grey. Its only in this state that the apps tray can be
relocated.
3. In a single motion, touch and hold the Multi window
tab for approximately one-second to detach it from
the screen (1), then slowly drag it to its new location on
any other available screen edge (2). You can move it to
the top or bottom of the screen, or to either side.
