"Insert building block" puts a ready-made instruction into the text at the position of the cursor, so that the syntax does not have to be typed or remembered. The menu offers, in order: - the blocks of the model, each with a submenu of its own; - the [[Invantive Composition for Word/Modeller/Edit Model/Parameters|parameters]]; - the [[Environment value|environment values]]. The submenu of a block starts with a building block which inserts a [[Possible instructions|foreach instruction]] over that block, and then lists the [[Variable value|variable values]] of its fields. Inserting the repetition first and a field afterwards therefore produces a working pair without either being typed.
