| iTool User's Guide: Working with Macros |

## Introduction

The macros in IDL iTools provide a shortcut mechanism that lets you quickly and automatically repeat a sequence of operations. You can record a series of actions in one iTool or several iTools, save the series as a macro, and then apply it to a new set of data to save you from having to repeat the actions manually.

This chapter discusses the following areas:

- More information about macros (see What Are Macros?)

- Recording macros (see Recording Macros)

- Running macros (see Running Macros)

- Editing macros (see Using the Macro Editor)

- Making selection and tool changes within a macro (see Making Selection and Tool Changes)

- Importing and exporting macros (see Importing and Exporting Macros)
