tab keys is good, what I meant is if I close unsaved file in textWrangler, it shows `Do you want to save` dialog. I press tab to focus 'Don't Save' button, press enter, but instead of closing file without saving I get 'Save As' dialog since enter key ignores the current focus and always triggers the default action
It's not a bug, just an odd convention, like using Enter to rename files in Finder.
Space = focused button, Enter = default button. When a dialog is shown, the focus is never on the default button, so there are always two choices that you can make (Space/Enter) without using the mouse or the tab key at all.
