If you want to do things like changing Action Properties programmatically you’ll have to do scripting … there is no other chance.
Dan‘s Dynamic Prompt for User Input Macro is one possible way to do it as well but as you’ll read there it requires an additional Plugin that has to be installed first.
Also this Macro - while it is great and very Valuable only supports some Properties not all of the Action.
The Action Timeout Property is actually not supported. I’m afraid - but it is totally worth it.
I am currently working on a Tutorial series based on the Scripting Topic where I‘ll also show a way to introduce how to handle Plugins that aren’t installed via Scripting. But I can’t say when it will be online. It seems I don’t have much time for it at the moment. Too much other work to do.
Maybe I’ll post an update to Dans Macro for all Properties that will also work for people who don’t want to install the Plugin , too.
We‘ll see …
