Situation description: When I rolled back the operation, I found that I couldn’t operate it suddenly. Sure enough, I didn’t see the shortcut key of Ctrl+Z when I opened the menu bar, but there was a shortcut key in another version. I remember that I added custom shortcut keys in the 2021.3.6 version. Perhaps due to misuse and interference between versions, the 2021.2.5 version of the shortcut keys disappeared.
Restore shortcut keys: Click Menu Bar-Edit-Shortcuts to open the shortcut key edit panel. Here we can see all shortcut key operations of the system and custom shortcut keys.
I found the command for the rollback operation. I found that there is a shortcut key, but there is no shortcut key in the menu bar. At this time, enter Ctrl+Z again to refresh, and the menu bar will be displayed, and the command will also take effect at this time.
