Can I get older (recent) versions of Keynote?

I have just updated Keynote to 10.0, and have noticed some loss of features. In particular, it seems the "typewriter" animation has been replaced with "keyboard". I recall having the option with typewriter (perhaps other animations too, I forget) to animate text by letter, so that they appeared at random. That is now gone. Can I either retrieve that feature, or else download the 9. Keynote from before this latest update? Any questions I have seen similar to this so far are trying to get really old versions. I just want to go back one version.
