Creating and Using Macros
You can record macros in the IDE to reduce what would normally involve a long set of keystrokes to one keyboard shortcut. In macros, you can combine the typing of characters in the Source Editor and the typing of other keyboard shortcuts.
To record a macro:
- Put the insertion point in the part of a file in the Source Editor where you want to record the macro.
- Click the
button in the Source Editor's toolbar (or press Ctrl-J and then type s) to begin recording. - Record the macro using any sequence of keystrokes, whether it is the typing of characters or using keyboard shortcuts. Mouse movements and clicks (such as menu selections) are not recorded.
- Click the
in the Source Editor's toolbar (or press Ctrl-J and then type e) to finish recording. - In the Macro field of the Recorded Macro dialog box that appears, fine-tune the macro, if necessary.
- Click Add to assign a keyboard shortcut to the macro.
- In the Add Keybinding dialog box, press the keys that you want to use for the keyboard shortcut. (For example, if you want the shortcut Alt-Shift-Z, press the Alt, Shift, and Z keys.) If you press a wrong key, click the Clear button to start over.

)
Be careful not to use a shortcut that is already assigned. If the shortcut you enter is an editor shortcut, a warning appears in the dialog box. However, if the key combination is a shortcut that applies outside of the Source Editor, you will not be warned.
You can assign a new shortcut in the Options window. Choose Tools | Options, click the Editor panel, select the Macros tab, and then click the Set Shortcut button.
