Delphi Form Designer doesn't undo changes

Question

In the Delphi Form Designer how do I undo changes. I press Ctrl + Z and nothing happens, I go to Edit -> Undo and it is grayed out.

Am I just missing something or does this just not work?

Also, if it does just not work, are there any plugins which I could install to fix it?

Nope, it just does not work. This feature has never been implemented.

Answer 2

As an update to this problem, this topic was re-opened in 2015 with a new feature request on the Embarcadero Quality Portal. The request was closed within weeks with a resolution of "Won't Fix", so not only does this feature not exist, Embarcadero has firmly now declared that they do not ever intend to provide this feature.
