Well a simple "grepping" showed that the "Read" activity is the only activity that explicitly makes use of the "KP_Home" and "KP_End" keys; but none seemed to make use of "KP_Prior" and "KP_Next". </div></div></blockquote><div> A simple grep is not good enough. Gtk already uses these keys, for example in a textview. I can't understand what you are trying to do. The user should press the key to enlarge/shrink the activity window? Does not look like a good solution.
