The Completion Menu
You can use the Completion menu to insert uses of defined terms (see Working with Defined Terms) and snippets (see Working with Snippets) into your document. When you start typing a use of a defined term or the name of a snippet, the Completion menu appears with a list of suggestions. You can continue typing to refine or ignore the suggestions. To choose a suggestion, use the Up Arrow and Down Arrow keys to select it, and then press the Right Arrow key. You can also choose a suggestion by clicking it.
To set Completion menu preferences, show the Contract Tools pane, click the Preferences button, and then use the Completion Menu controls.
