Deleting Animation Keys

HOw can I delete animation keys? I noticed that i added far too many…and then i couldn’t figure out how to get rid of them all…

change any window into an IPO window (SHIFT+F6), move the mouse over it and press “K”. you’ll notice that vertical lines have appeared - these are the keys of the selected objects. you can select them and then, pressing “X”, delete them.

you can also do that in the NLA editor (only available from each window-menu). every key is displayed by grey/yellow rectangles. deleting goes the same way (“X”)
