Abstract: A consume-first mode for an editor is automatically entered if one or more predefined heuristic conditions are met. Some examples of heuristic conditions include conditions indicating that a user will be entering computer program source code during test-driven development, user action to undo autocompletion, and expected entry of a dynamically typed item identifier. In addition to heuristic consume-first mode, some editors recognize an explicit command to enter or exit the consume-first mode. A list of completion suggestions may be displayed in the consume-first mode, but autocompletion is turned off. An identifier may also be preemptively included on a suggested completions list for use before a user has entered that identifier using the editor.
