You cannot play a macro when recording is in progress or when another macro is playing.
To play the current temporary macro
Select the Macro command from the Edit menu and then select the Play Temp Macro command from the submenu that is displayed.
The current temporary macro is then played in the editor pane.
Macro replay halts when you move the caret outside the document limits (before the start or after the end of the method in the editor pane) or when a Find command has no match.
