When I press Command ⌘+↑ or Command ⌘+↓ on OS X 10.8.2 (Mountain Lion), it scrolls all the way to the top or the bottom of a window.
The problem is, in some programs, this results in crazy uncontrollable scrolling behavior, because for whatever reason the program doesn't signal to the OS that it's hit the end of its scrolling. It's driving me nuts.
Is there any way to turn off this behavior? I've searched System Preferences > Keyboard settings to no avail.
