Modifying Opera to allow 2-d scrolling with the scroll key
This HOWTO describes a method for allowing easier 2-d scrolling with the scroll key, instead of using the stylus. It is no longer accurate since the 2006 OS update does not allow changing the functionality of the zoom keys any longer.
Background
I find it very annoying to select URLs with the scroll key and navigate with the stylus, it seems much more natural to do the opposite. Fortunately Opera allows this.
Modifying Opera
This requires a small change to ~/.opera/input.ini, replace:
Right = Navigate right Left = Navigate left Down = Navigate down Up = Navigate up
With:
Right = Scroll right Left = Scroll left Down = Scroll down Up = Scroll up
Or possibly:
Right = Scroll right Left = Scroll left Down = Page down Up = Page up
To reconfigure the scroll button actions when held down use:
Left_long = Scroll left Right_long = Scroll right Up_long = Scroll up Down_long = Scroll down
Exit the browser and restart. Enjoy using the scroll button to control the view and the stylus as a mouse replacement. If anyone knows how to change the stylus click to loading a page in the background please let me know.
Additonally:
You can also map the Zoom Rocker Switch at the top to scroll up and down by making this change:
F7 = Page Down F8 = Page Up
If scrolling a page is too much, and scrolling a couple of lines is not enough, you can also combine multiple actions to a key. As an example, you can do something like this:
Down = Scroll down & Scroll down Up = Scroll up & Scroll up
This makes the up and down keys scroll twice as much as they would normally. You can increase the scroll size more by adding additional actions separated by the "&" symbol.
What seems to work well is mapping F7 and F8 (The zoom rocker switches) to page down and up, and the up and down d-pad keys to scrolling at a double rate. This allows quick movement through a web page, and still allows you to "fine tune" using the d-pad and not having to resort to using the stylus to move the screen around.
