The answer command displays a dialog box containing the result of an expression. While its not yet implemented, you can also display a question and up to three response buttons, each representing a different possible reply. Additionally, and once again not yet implemented, you can use answer file to prompt the user for a file from their computer, optionally providing an extra parameter "of type" to filter their choices to a certain file type.

NOTE: This command has not been implemented yet, but will be soon. The wait command causes the system to pause before executing the rest of the handler, either for a specific length of time, until a specified condition becomes true, or a while a specified condition remains true.
