One thing I do a lot is Command ⌘-Tab over to TextEdit, jot down some notes, and then decide to throw them away. I can close the window with ⌘-W, but is there a way to not-save it from just the keyboard?
Escape simply cancels the close. ⌘-D takes the file-picker to the Desktop (and I thought this used to work, pre-Lion, but maybe I'm just imagining it).
Is there a keyboard shortcut for Don't Save, short of turning on Full Keyboard Access?
