The process works basically the same way on the T3 that's outlined in this post. Follow the steps outlined there to register and refer to the info I've provided below to locate the menu.

On the T3 you have two different menu "buttons" - one is on the taskbar silkscreen (just to the left of the time display), and the other can be found on the "classic" display of the input silkscreen (unless you reassigned those icons). To access the "classic" input area, tap and hold the icon on the far right of the taskbar silkscreen and choose the bottom one.
