Here’s the plug-in:
MacroStepThrough.ny (1.38 KB)
When installed it will appear in the Tools menu.
The way that I’m using it is to set a keyboard shortcut ("Ctrl + ", but for no other reason than it’s available).
To step through requires two key pressess: "Ctrl + " then “Enter”.
On completion of the Macro, the plug-in automatically resets.
To force a reset before the Macro has completed, either enter an invalid Macro name, or leave the Macro name empty.
