In the Formatting category, Authorizations, objects may be kept from being put in Select or Edit mode by selecting one of three options to enable these authorizations: always allow, never allow, or custom to evaluate a conditional statement.  If the conditional statement under Custom evaluates to true, the user can select and/or edit the object as allowed.

In the example below, a permission rule is created to prohibit objects from being resized and repositioned.  Unlike authorizations, a message will appear alerting the user that s/he cannot perform the attempted action.  A permission rule may take effect when conditional statements evalute to true in the Rule Formula edit box of the Permission Rules dialog.
