On the Desire Z, in the settings for keyboard shortcuts you have shortcut key #1 and #2 which correspond to the [:.1] and [:.2] hardware buttons on the lower right of the keyboard. Easy enough to use. How on earth do you use the Shortcut key #A/B/C? It says to press and hold on Home? Does that mean long press on the home touchscreen button? That just brings up the multitask switcher.
