Question
The undo shortcut is not working in the after effects CC.


Hi,
I just installed after effects CC.
But the undo key doesn't work.
The shortcut is definitely Ctrl+z.
But I press Ctrl+z, it doesn't react.
The same goes for running Edith > Purge >undo.
It deactivates without a response.
Only undo not working.
It was the same when I reinstalled CC.
It's making me crazy.
