You’ve got the right idea, but I’m not sure what you expect is what your users would expect? Am I understanding it correctly that a user would:
1. Open your UI 2. Click a button 3. Think for a moment.. 4. Click another button 5. Check their phone.. 6. Click a third button 7. Close the UI And then when they hit Ctrl + Z it would undo each of these 3 button presses? If it was me, I would expect 3 clicks to require 3 undos. If you really did want to undo each of the three items, then you’re on a bit of thin ice but not impossibly thin. You can: 1. On window open, open that undo chunk 2. Let the user click buttons 3. On window close, close the undo chunk That way, the next undo would undo all of it. The reason it’s thin ice is because the undo chunk is global to Maya and would include anything they do outside of it also. So the next undo may take other things with it that falls outside of your control. Generally, undo has a temperament and should be dealt with cautiously. It can easily break other undo’s in the queue and often bring Maya down with it. So if you can, I would recommend you do what Maya does naturally and avoid undoInfo.
