I have bindings in various places which use Shift + cursor up/down, e.g. in my .inputrc for searching through things like shell command history. I often type the first few letters of a command then press Shift + cursor up, and got a bit of a surprise when Terminal scrolled the window a little.

As a result, I patched Terminal so that this behaviour could be disabled.

I also decided to allow Shift+F10 to be passed on to whatever's running in the terminal (since it's possible that people who've been using xterm may be using that for something else).
