A keystroke macro (not to be confused with POV-Ray scene file macros) is a collection of editing actions (which may include cursor movement, text editing, search, replace, and so forth) which may be assigned to a shortcut key and stored for re-use. POV-Ray for Windows stores macros in the registry, so they will still be available next time you run the program. You can have up to ten keystroke macros recorded at any one time.

Once you activate the 'Record Macro' command, a small dialog box will appear that allows you to stop the recording, and then assign a key to the macro before it is saved. If you do not assign a key, the macro will still be playable via the 'Play Macro' menu. Editor Preferences Dialog Auto-Reload
