I frequently want to scroll the display without moving the cursor. As for selecting lines, you do realize that Ctrl+A and Ctrl+E work everywhere in OS X, right? Generally whenever I select an entire line, I do so to erase, move, or duplicate it, and Cocoa's Emacs-style shortcuts are much nicer than Windows/CUA-style shortcuts for these operations (and difficult to support on systems where Ctrl is used for menu command accelerators).

Far more frequently, I want to delete from the current cursor position to the end of a line, and Ctrl+K is much nicer than Shift+End, Backspace.
