I now have so many useful macros that I'm running out of easy to press keyboard shortcuts. I've read about ways to use smart keyboard shortcuts, organised in groups etc.
Before I dive into that approach, I'd like to investigate another approach: flexible palettes or macro bars to which I can simply add macros by activating a checkbox in their actions.
So, for a specific job I need a macro to make every letter after a line break uppercase, a macro to replace spaces with line breaks, a macro to replace round brackets with square brackets etc.
I open these macros and click a checkbox to add them to a vertical or horizontal palette or bar.
Just add all useful macros to a palette, or duplicate them to several palettes for specific projects.
(Or perhaps better: use placeholders (macros that call macros) to add them to several palettes, to keep only one instance of every macro, to simplify modification/debugging.)
And activate them ad libitum. (The magic switch I needed.)
Yes, you might prefer to create an Alias (Edit > Make Alias).
So you keep the original macro in its original macro group, and just move this newly created alias to a separate macro group.
