Undo doesn't work with everything

But maybe it’s just because I have to use an old (22.12.21) version on my Windows 7 computer. It always works with, say, moving a clip, but it doesn’t work with things like adjusting keyframes and you can really get into trouble with them. Ask me how I know this, lol.

Is the Undo feature more comprehensive in newer versions?

Undo doesn’t work on keyframes in your version.

But it was added in version 24.04 on some selected filters:

Version 24.01 added undo for filters

Ah well, that explains it. Thanks, guys.
