I have a bunch of keyboard shortcut driven AppleScripts for opening various folders in the Finder. Too many in fact – I'm running out of viable keyboard shortcuts.
So I created a macro that uses a Prompt With List action with a list of folder paths as its source.
This is easy to customize and relieves my memory of the burden of remembering more keyboard shortcuts.
Keyboard Maestro was not designed to replace Alfred.
Personally I would never give up LaunchBar in lieu of Keyboard Maestro, because it does things KM and other utilities don't.
I could probably switch to Alfred if I had to, but I've been using LaunchBar for much too long (20+ years) to switch without a very compelling reason.
I also use Typinator for text replacement, as it is far more efficient for that job than Keyboard Maestro. (48820 snippets and counting.)
No one would expect Keyboard Maestro to replace all other utilities.
It's just that Keyboard Maestro has the ability to make the impossible possible on a Mac, and it has the ability to make your Mac work more the way you want it to.
