Nope, sorry. You can, of course, write your own macro that prompts for a value and adds it to your list. I know it's not the same, but that's all I got. (Although it sounds like a good option, but I don't have the time to add it as a feature.)
@Jamag Well, one possible way of doing it would be to use a "custom button", which is explained when you launch the "Spotlight Search Prompt Documentation" macro. You could have a button that says "Add". Unfortunately, it won't return the value entered in the search field, but you could at least use it to run another macro that prompts you for the value, and adds it to your list.
Thanks! I feel that way in general about Keyboard Maestro, but then, I suppose most of us feel that way. It's such an integral part of my everyday workflow that I can't even imagine life without it!
Thanks, Chris. Honestly, I use it so often that I sometimes forget that I wrote it! You know you created something good when you even impress yourself!
I assume you mean you got the error when running the Spotlight Search Prompt Documentation macro (You don't run the Spotlight Search Prompt macro by itself).
Try running this macro first: Spotlight KM Variables. It'll finish in an instant and won't display anything. Then run the Spotlight Search Prompt Documentation macro, and it should work OK. I hope.
