The default access control values implement the basic rules detailed in section 4.7.2.2 -- full access rights for Workspace members, no access rights for other users. Thus, modifications will reduce the access rights of 'Members' or grant access rights to 'Other users'. This is achieved by choosing a different access control value from the menu in the appropriate cell of the Access control table:
icon to the left of the object's type icon to display the object's Info page.
on the top button bar in the Info page to bring up the 'Access control table for object name' form.
to explicitly deny Workspace members the right to perform the actions of the cluster controlled by this column.
Or
to explicitly grant other users the right to perform the actions controlled by this column.
The access control values of 'Members ...' or 'Other users' for the same action cluster may be chosen independent of one another.
