For Mac users who might not know, the standard text widgets in OS X use a subset of Emacs keybindings, so you can use C-a, C-e, etc to quickly navigate, which is handy if you have your Caps Lock key remapped to Ctrl (in the Keyboard system preferences) and are used to Emacs. Two caveats: 1) no meta key, which makes navigation less handy sometimes; 2) C-k will kill the line, but I haven't found a kill-ring and you can't use C-y to yank the line back! This has bitten me a couple of times. It's definitely nothing close to having a full text editing Emacs widget, but I've found it handy.
