({{, Initialization Group
makes the cells in a group auto-evaluate whenever the notebook is opened and the kernel is launched.}})

OpenersNotesSection(Spacer1)Details

When a cell group is an initialization group, a vertical tick mark (|) appears in each cell bracket in the group.

Initialization Group sets the option (RefLink[InitializationGroup, paclet:ref/InitializationGroup]) for the leading cell in the initialization group.

The option (RefLink[InitializationCellEvaluation, paclet:ref/InitializationCellEvaluation]), set at the notebook level, determines when single or grouped initialization cells in a notebook are evaluated.

The option (RefLink[InitializationCellWarning, paclet:ref/InitializationCellWarning]) determines whether you get a dialog box confirming that you want to evaluate the initialization cells or groups, at the time determined by (RefLink[InitializationCellEvaluation, paclet:ref/InitializationCellEvaluation]).

You can evaluate all of the initialization cells manually at any time by choosing (MenuGrayLink[Evaluation, paclet:guide/EvaluationMenu]) ▶ (MenuGrayLink[Evaluate Initialization Cells, paclet:ref/menuitem/EvaluateInitializationCells]).
