In the Source Editor, position the insertion point where you want to run
the macro, and type the macro's keyboard shortcut.
To find the keyboard shortcut for a macro:
Choose Tools Options
and expand the editing node. Then expand the Editor Settings node and select
the type of editor you are using.
Click the Key Bindings property, and then click the ellipsis (...) button
to display the list of keyboard shortcuts for your editor type.
Scroll about halfway down in the Actions list until you find macros.
All macro actions start with macro-. The actions are sorted
alphabetically by the name in brackets.
Select the macro you want to start. Keyboard shortcuts for that macro are
displayed in the Shortcut Sequences field.
If you want to see or edit the macro definition, click the Macros property
in Step 2 instead of the Key Bindings property.
