Name	Description
::root	contains the object the expression is evaluated for. ::root is identical to `cooobj`.
::attribute	contains the property the expression is evaluated for.
::parent	the parent of `cooobj`.
::value	the current value of the property
::isvalue	contains `true` if the form is used for displaying values (edit mode or read-only mode) opposed to query mode (see `valuetype` in `ApplicationView`).
::isedit	contains `true` if the form is in edit mode opposed to read-only mode (see `edittype` in `ApplicationView`). ::isedit is only valid if ::isvalue is `true`.
::iseditcommon	contains `true` if the form is used to edit common properties of multiple objects. ::iseditcommon is only valid if ::isvalue is `true`. In this case ::root/`cooobj` refer to the first object of the selection.
::isdashboard	contains `true` if the property is displayed in a dashboard.
::iscalccelledit	contains `true` if the property is displayed while editing in a cell (F2).
::issingleattribute	contains `true` if the property is displayed in single attribute mode, i. e. when all other properties of a form page are hidden.
::context	contains the view action which is used to determine the form. Typical view actions are: `ObjectConstructor` `EditObjectAttributes` `OpenAllObjectAttributes` `ReadObjectAttributes` `CreateObject` `ExploreObject` `ObjectInfo` `OverviewObject` `Preview` `RenameObject` `SimpleContView` `SimpleCardView` `ZoomReadObject` `SearchObjects` `ExploreTextModule` `SignSelectedObjectsManual` `InitGUI` `EditSettings` `EditObjectLogo` `InitGUI` `ManageSecuritySettings` `ReadProcessObjectAttributes`
