Sun's patch 120289 recently change gnome-terminal's behavior on page up and page down keys. Some people are very happy about this:
Unfortunately, I'm not. *grin*
I do understand why the change was made --- usability matters! --- but for me, the existing behavior was perfectly usable and right: I want those keys to be sent to the terminal. I use those keys all the time in pine, and they don't work anymore.
I'm now trying to figure out how to work with gconf-editor to preserve the old behavior but haven't figured out where things need to change yet. Oh well.
