in the documents list.Applies to MindManager used with Mindjet Catalyst.
If you don't want anyone else to make changes to a document you can lock it. Other members can still view the document but they cannot edit it, and they will see that you have the document locked in the documents list.
You can lock a map either before or after you open it. If you lock a map while other members are editing it, you'll see a warning, and if you proceed with the lock they will no longer be able to make changes to the map.
Members who view locked maps will see the lock information in the Map Status indicator in the upper-left of the Map View.
To show or hide the Map Status indicator, on the MindManager View tab, in the Activity group, click Map Activity, then click Show Map Status.
Files (non-map documents) are automatically locked when they are checked out for editing, and unlocked when they are checked in, but you can also manually lock and unlock them.
Members with Reader access for the workspace cannot lock documents.
Do one of the following:
Select the document in the Documents list, then on the Workspaces tab, in the Document Access group, click Lock.
Right-click the document name in the Documents list then click Lock.
The "Locked by me" 
icon in the Documents list indicates documents that you have locked. You will also see this icon in the Map Status indicator if you edit the map.
Unlock the document by following the same steps, but click Unlock.
Workspace Owners can break locks on documents locked or checked out 
by other members:
Select the document in the Documents list, then on the Workspaces tab, in the Document Access group, click Break Lock.
If possible, contact the user who has the document locked or checked out before breaking the lock. This allows them to create a copy of the locked map for their personal use, or check in the changes they have made to the checked-out file.
If you break the lock on a file that was checked out, the checkout is discarded and another user can then edit the file. Any changes made to the file by the user who did not check it back in are retained only in that users local copy of the file, and that user will see the file's Local Copy status change to Unresolved.
If you leave a workspace or if you are removed from the workspace by another member all your locks are removed.
