hi, this is to eliminate the hassle of using stylus to drag scrollbar to navigate webpage.
To enable page up/down/left/right. Do the following:

Page UP/Down/Left/Right a full screen at a time
By default Opera moves to the next object on the web page as you press the up, down, left, right buttons. This modification will scroll an entire page as you press each button.
1) Edit the "input.ini" file located in "\Application Data\Opera"
2) Go to the "[Browser Widget]" group
3) Change "Down = Navigate down" to "Down = Page down"
4) Change "UP = Navigate up" to "UP = Page up"
5) Change "Left = Navigate left" to "Down = Page left"
6) Change "Right = Navigate right" to "UP = Page right"


Turn off the scroll bars
This turns off the up/down scroll bars and gets some screen space back for viewing. This works great in conjunction with the modification listed above.
1) Edit the "opera.ini" file located in "\Application Data\Opera"
2) Go to the "[User Prefs]" group
3) Change "Show Scrollbars=1" to "Show Scrollbars=0"
