Ikbel,

How do you map applications to windows? Is it based on the window title?
If so, I suggest defining the "Application" property as a regex so
titles can be matched easily no matter what their format.

As for the triggers, I think some suggestions would be helpful. For
example, if gtk scroll events shift contents of a window by 30 pixels,
then a suggested trigger for a scroll event through ginn should be 30
pixels. That way a user can scroll a document and there will be a
one-to-one mapping between physical and screen space.

If toolkits have a way to dynamically set the scroll amount, it might be
worthwhile to define a trigger that is in scroll sizes, like "1S" might
mean 1 scroll size, which would translate to 30 pixels in the above
scenario. I'm not sure how feasible this is, but it's worth taking a
look at.

Otherwise, I like the concepts here.
