You can accelerate the dictionary use into a book avoiding entering into the menu.
Go to the configuration of keys on the device options. Select the key you want (long press or short, I have configured the joystick UP short) to open the dictionary.
From that moment, every time you press that button will open the dictionary automatically. The time it takes to do this is the time you need to remove the stylus and tap the screen.
It seems a silly option but it accelerates word search... And you can configure other fancy things in same way.
